Convert the s390 CPU to the Resettable interface. This is slightly
more involved than the other CPU types were (see commits
9130cade5fc22..d66e64dd006df) because S390 has its own set of
different kinds of reset with different behaviours that it needs to
trigger.
We handle this by adding these reset types to the Resettable
ResetType enum. Now instead of having an underlying implementation
of reset that is s390-specific and which might be called either
directly or via the DeviceClass::reset method, we can implement only
the Resettable hold phase method, and have the places that need to
trigger an s390-specific reset type do so by calling
resettable_reset().
The other option would have been to smuggle in the s390 reset
type via, for instance, a field in the CPU state that we set
in s390_do_cpu_initial_reset() etc and then examined in the
reset method, but doing it this way seems cleaner.
The motivation for this change is that this is the last caller
of the legacy device_class_set_parent_reset() function, and
removing that will let us clean up some glue code that we added
for the transition to three-phase reset.

Convert the virtio-ccw code to three-phase reset. This allows us to
remove a call to device_class_set_parent_reset(), replacing it with
the three-phase equivalent resettable_class_set_parent_phases().
Removing all the device_class_set_parent_reset() uses will allow us
to remove some of the glue code that interworks between three-phase
and legacy reset.
This is a simple conversion, with no behavioural changes.

The cross-i686-tci CI job is persistently flaky with various tests
hitting timeouts. One theory for why this is happening is that we're
running too many tests in parallel and so sometimes a test gets
starved of CPU and isn't able to complete within the timeout.
(The environment this CI job runs in seems to cause us to default
to a parallelism of 9 in the main CI.)

When qemu runs without kvm acceleration the ACPI executions take a great
amount of time. If they take more than the default time (30sec), the
ACPI calls fail and the system might not behave correctly.
Now the _PRT table is computed on the fly. We can drastically reduce the
execution of the _PRT method if we return a pre-computed table.

According to spec, invalidation descriptor type is 7bits which is
concatenation of bits[11:9] and bits[3:0] of invalidation descriptor.
Currently we only pick bits[3:0] as the invalidation type and treat
bits[11:9] as reserved zero. This is not a problem for now as bits[11:9]
is zero for all current invalidation types. But it will break if newer
type occupies bits[11:9].
Fix it by taking bits[11:9] into type and make reserved bits check accurate.

When BAR aren't mapped, we get:
(qemu) info pci
Bus 0, device 0, function 0:
Host bridge: PCI device dead:beef
...
BAR4: 32 bit memory at 0xffffffffffffffff [0x00000ffe].
BAR5: I/O at 0xffffffffffffffff [0x0ffe].
Check the BAR is mapped comparing its address to PCI_BAR_UNMAPPED
which is what the PCI layer uses for unmapped BARs.
See pci_bar_address and pci_update_mappings implementations and
in "hw/pci/pci.h":
typedef struct PCIIORegion {
pcibus_t addr; /* current PCI mapping address. -1 means not mapped */
#define PCI_BAR_UNMAPPED (~(pcibus_t)0)
...
This improves the logging, not displaying bogus sizes:
(qemu) info pci
Bus 0, device 0, function 0:
Host bridge: PCI device dead:beef
...
BAR4: 32 bit memory (not mapped)
BAR5: I/O (not mapped)
Remove trailing dot which is not used in other commands format.

When the devfn is already assigned in the command line, the
do_pci_register_device() may verify if the function 0 is already occupied.
However, when devfn < 0, the verification is skipped because it is part of
the last "else if".
For instance, suppose there is already a device at addr=00.00 of a port.
-device pcie-root-port,bus=pcie.0,chassis=115,id=port01,addr=0e.00 \
-device virtio-net-pci,bus=port01,id=vnet01,addr=00.00 \
When 'addr' is specified for the 2nd device, the hotplug is denied.
(qemu) device_add virtio-net-pci,bus=port01,id=vnet02,addr=01.00
Error: PCI: slot 0 function 0 already occupied by virtio-net-pci, new func virtio-net-pci cannot be exposed to guest.
When 'addr' is automatically assigned, the hotplug is not denied. This is
because the verification is skipped.
(qemu) device_add virtio-net-pci,bus=port01,id=vnet02
warning: PCI: slot 1 is not valid for virtio-net-pci, parent device only allows plugging into slot 0.
Fix the issue by moving the verification into an independent 'if'
statement.
