We pass a ResetType argument to the Resettable class enter
phase method, but we don't pass it to hold and exit, even though
the callsites have it readily available. This means that if
a device cared about the ResetType it would need to record it
in the enter phase method to use later on. Pass the type to
all three of the phase methods to avoid having to do that.

A few watchdog devices use qemu_system_reset_request(). This is not ideal since
behaviour of watchdog-expiry can't be changed by QMP using `watchdog_action`.
As stated in BiteSizedTasks wiki page, instead of using qemu_system_reset_request()
to reset when a watchdog timer expires, let watchdog_perform_action() decide
what to do.

The nrf51_timer has a free-running counter which we implement using
the pattern of using two fields (update_counter_ns, counter) to track
the last point at which we calculated the counter value, and the
counter value at that time. Then we can find the current counter
value by converting the difference in wall-clock time between then
and now to a tick count that we need to add to the counter value.
Unfortunately the nrf51_timer's implementation of this has a bug
which means it loses time every time update_counter() is called.
After updating s->counter it always sets s->update_counter_ns to
'now', even though the actual point when s->counter hit the new value
will be some point in the past (half a tick, say). In the worst case
(guest code in a tight loop reading the counter, icount mode) the
counter is continually queried less than a tick after it was last
read, so s->counter never advances but s->update_counter_ns does, and
the guest never makes forward progress.
The fix for this is to only advance update_counter_ns to the
timestamp of the last tick, not all the way to 'now'. (This is the
pattern used in hw/misc/mps2-fpgaio.c's counter.)

The expiration time provided for timer_mod() can overflow if a
ridiculously large value is set to the comparator register. The
resulting value can represent a past time after rounded, forcing the
timer to fire immediately. If the timer is configured as periodic, it
will rearm the timer again, and form an endless loop.
Check if the expiration value will overflow, and if it will, stop the
timer instead of rearming the timer with the overflowed time.

The 'hwaddr' type is defined in "exec/hwaddr.h" as:
hwaddr is the type of a physical address
(its size can be different from 'target_ulong').
All definitions use the 'HWADDR_' prefix, except TARGET_FMT_plx:
$ fgrep define include/exec/hwaddr.h
#define HWADDR_H
#define HWADDR_BITS 64
#define HWADDR_MAX UINT64_MAX
#define TARGET_FMT_plx "%016" PRIx64
^^^^^^
#define HWADDR_PRId PRId64
#define HWADDR_PRIi PRIi64
#define HWADDR_PRIo PRIo64
#define HWADDR_PRIu PRIu64
#define HWADDR_PRIx PRIx64
#define HWADDR_PRIX PRIX64
Since hwaddr's size can be *different* from target_ulong, it is
very confusing to read one of its format using the 'TARGET_FMT_'
prefix, normally used for the target_long / target_ulong types:
$ fgrep TARGET_FMT_ include/exec/cpu-defs.h
#define TARGET_FMT_lx "%08x"
#define TARGET_FMT_ld "%d"
#define TARGET_FMT_lu "%u"
#define TARGET_FMT_lx "%016" PRIx64
#define TARGET_FMT_ld "%" PRId64
#define TARGET_FMT_lu "%" PRIu64
Apparently this format was missed during commit a8170e5e97
("Rename target_phys_addr_t to hwaddr"), so complete it by
doing a bulk-rename with:
$ sed -i -e s/TARGET_FMT_plx/HWADDR_FMT_plx/g $(git grep -l TARGET_FMT_plx)

The traditional ptimer behaviour includes a collection of weird edge
case behaviours. In 2016 we improved the ptimer implementation to
fix these and generally make the behaviour more flexible, with
ptimers opting in to the new behaviour by passing an appropriate set
of policy flags to ptimer_init(). For backwards-compatibility, we
defined PTIMER_POLICY_DEFAULT (which sets no flags) to give the old
weird behaviour.
This turns out to be a poor choice of name, because people writing
new devices which use ptimers are misled into thinking that the
default is probably a sensible choice of flags, when in fact it is
almost always not what you want. Rename PTIMER_POLICY_DEFAULT to
PTIMER_POLICY_LEGACY and beef up the comment to more clearly say that
new devices should not be using it.
The code-change part of this commit was produced by
sed -i -e 's/PTIMER_POLICY_DEFAULT/PTIMER_POLICY_LEGACY/g' $(git grep -l PTIMER_POLICY_DEFAULT)
with the exception of a test name string change in

g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer,
for two reasons. One, it catches multiplication overflowing size_t.
Two, it returns T * rather than void *, which lets the compiler catch
more type errors.
This commit only touches allocations with size arguments of the form
sizeof(T).

A9 gtimer includes global control field and number of per-cpu fields.
But only per-cpu ones are migrated. This patch adds a subsection for
global control field migration.

Starting the SysTick timer and changing the clock source a the same time
will result in an error, if the previous clock period was zero. For exmaple,
on the mps2-tz platforms, no refclk is present. Right after reset, the
configured ptimer period is zero, and trying to enabling it will turn it off
right away. E.g., code running on the platform setting
SysTick->CTRL = SysTick_CTRL_CLKSOURCE_Msk | SysTick_CTRL_ENABLE_Msk;
should change the clock source and enable the timer on real hardware, but
resulted in an error in qemu.

The following changes:
1. Fixes the incorrectly set CTRL register address. As
per [1] https://docs.opentitan.org/hw/ip/rv_timer/doc/#register-table
The CTRL register is @ 0x04.
This was found when attempting to fixup a bug where a timer_interrupt
was not serviced on TockOS-OpenTitan.
2. Adds ALERT_TEST register as documented on [1], adding repective
switch cases to error handle and later implement functionality.

The hw_error function calls abort and is not meant to be used by
devices. Use qemu_log_mask instead to log and ignore invalid accesses.
Also fix format strings to allow dropping type casts of hwaddr and use
__func__ instead of hard coding function name in the message which
were wrong in two cases.
