LegacyReset does not pass ResetType to the reset callback method, which
the new Resettable framework uses. Due to this, virtio-mem cannot use
the new RESET_TYPE_WAKEUP to skip the reset during wake-up from a
suspended state.
This patch adds overrides Resettable interface methods in VirtIOMEMClass
to use the new Resettable framework and replaces
qemu_[un]register_reset() calls with qemu_[un]register_resettable().

Some devices need to distinguish cold start reset from waking up from a
suspended state. This patch adds new value to the enum, and updates the
i386 wakeup method to use this new reset type.

Currently, both qemu_devices_reset() and MachineClass::reset() use
ShutdownCause for the reason of the reset. However, the Resettable
interface uses ResetState, so ShutdownCause needs to be translated to
ResetType somewhere. Translating it qemu_devices_reset() makes adding
new reset types harder, as they cannot always be matched to a single
ShutdownCause here, and devices may need to check the ResetType to
determine what to reset and if to reset at all.
This patch moves this translation up in the call stack to
qemu_system_reset() and updates all MachineClass children to use the
ResetType instead.

Virtio memory devices rely on PCI BARs to expose the contents of memory.
Because of this they cannot be used (yet) with virtio-mmio or virtio-ccw.
In fact the code that is common to virtio-mem and virtio-pmem, which
is in hw/virtio/virtio-md-pci.c, is only included if CONFIG_VIRTIO_PCI
is set. Reproduce the same condition in the Kconfig file, only allowing
VIRTIO_MEM and VIRTIO_PMEM to be defined if the transport supports it.
Without this patch it is possible to create a configuration with
CONFIG_VIRTIO_PCI=n and CONFIG_VIRTIO_MEM=y, but that causes a
linking failure.

The XT check for the lxvx/stxvx instructions is currently
inverted. This was introduced during the move to decodetree.
>From the ISA:
Chapter 7. Vector-Scalar Extension Facility
Load VSX Vector Indexed X-form
lxvx XT,RA,RB
if TX=0 & MSR.VSX=0 then VSX_Unavailable()
if TX=1 & MSR.VEC=0 then Vector_Unavailable()
...
Let XT be the value 32×TX + T.
The code currently does the opposite:
if (paired || a->rt >= 32) {
REQUIRE_VSX(ctx);
} else {
REQUIRE_VECTOR(ctx);
}
This was already fixed for lxv/stxv at commit "2cc0e449d1 (target/ppc:
Fix lxv/stxv MSR facility check)", but the indexed forms were missed.

The sse/avx instruction set only has EQ and GT as direct comparisons.
Other signed comparisons can be generated from swapping and inversion.
However unsigned comparisons are not available and must be transformed
to signed comparisons by biasing the inputs.
The avx512 instruction set has a complete set of comparisons, with
results placed into a predicate register. We can produce the normal
cmp_vec result by using VPMOVM2*.

suited for running the iotests than the or1k default machine since
it provides PCI and thus e.g. support for virtio-blk and virtio-scsi,
too. With this change, there are no failing iotests anymore when
