It's respin of v14* series which uses a PCI BAR to map
VGID page in guest AS.
Changes since v14:
- statically reserve used BAR resources in SSDT, so
that Windows won't claim them during PCI rebalancing
- support VGID page in high mem in addition to low mem
- add QMP/HMP interfaces to get/set VM Generation ID
- do not consume a PCI slot by default and attach
vmgenid device as a function of multifuction
ISA bridge.
- allow only one vmgenid device instance
Tested with WS2012R2x64.
