This patch converts the old "is_write" bool into IOMMUAccessFlags. The
difference is that "is_write" can only express either read/write, but
sometimes what we really want is "none" here (neither read nor write).
Replay is an good example - during replay, we should not check any RW
permission bits since thats not an actual IO at all.

The JAZZ RC4030 chipset emulator has a periodic timer and
associated interval reload register. The reload value is used
as divider when computing timer's next tick value. If reload
value is large, it could lead to divide by zero error. Limit
the interval reload value to avoid it.

This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed. This replacement improves the readability and
understandability of code.
For example,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

Now that rc4030 internally uses an AddressSpace for DMA handling, make its root
memory region public. This is especially usefull for dp8393x netcard, which now
