i386: Make Hyper-V version id configurable
Currently, we hardcode Hyper-V version id (CPUID 0x40000002) to
WS2008R2 and it is known that certain tools in Windows check this. It
seems useful to provide some flexibility by making it possible to change
this info at will. CPUID information is defined in TLFS as:
EAX: Build Number
EBX Bits 31-16: Major Version
Bits 15-0: Minor Version
ECX Service Pack
EDX Bits 31-24: Service Branch
Bits 23-0: Service Number
