powerpc: add PVR mask support

IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and
a CPU version in lower 16 bits. Since there is no significant change
in behavior between versions, there is no point to add every single CPU
version in QEMU's CPU list. Also, new CPU versions of already supported
CPU won't break the existing code.

This adds PVR value/mask support for KVM, i.e. for -cpu host option.

As CPU family class name for POWER7 is "POWER7-family", there is no need
to touch aliases.

spapr: add vio-bus devices to categories

In order to get devices appear in output of
"./qemu-system-ppc64 -device ?",
they must be assigned to one of DEVICE_CATEGORY_XXXX.

This puts VIO devices classes to corresponding categories.

PPC: fix PCI configuration space MemoryRegions for grackle/uninorth

OpenBIOS prior to SVN r1225 had a horrible bug when accessing PCI
configuration space for PPC Mac architectures - instead of writing the PCI
configuration data value to the data register address, it would instead write
it to the data register address plus the PCI configuration address.

For this reason, the MemoryRegions for the PCI data register for
grackle/uninorth were extremely large in order to accomodate the entire PCI
configuration space being accessed during OpenBIOS PCI bus enumeration. Now
that the OpenBIOS images have been updated, reduce the MemoryRegion sizes down
to a single 32-bit register as intended.
