acpi: piix4: remove not needed GPE0 mask

Hardcoded GPE0 mask isn't really needed. Since GPE0_STS initialized
with all bits cleared and only QEMU itself can set bits there (i.e.
guest can only clear bits in it). So guest can't triger SCI
by setting _STS & _EN bits and there is not reason to mask out not...

qdev: Drop misleading qdev_free() function

The qdev_free() function name is misleading since all the function does
is unlink the device from its parent. The device is not necessarily
freed.

The device will be freed when its QObject refcount reaches zero. It is...

piix: APIs for pc guest info

This adds APIs that will be used to fill in guest acpi tables.
Some required information is still lacking in QOM, so we
fall back on lookups by type and returning explicit types.

Currently Xen hvm s3 has a bug coming from the difference between

piix4: disable io on reset

io base register at 0x40 is cleared on reset,
but io is not disabled until some other event
happens to call pm_io_space_update.

Invoke pm_io_space_update directly to make this
consistent.

cpu: Replace qemu_for_each_cpu()

It was introduced to loop over CPUs from target-independent code, but

CPUState is used.

A loop can be considered more efficient than function calls in a loop,...
