arm64: enablement for ARM64 in Hyper-V (Part 1)
The changes are to refactor the code of vmbus.c and hyperv.c to keep minimal arch specific codes there and have them in separate files in x86/ arm64/ . x86 is a new directory, which contains codes for x86 / x86_64. Instead of repeating the same codes in existing amd64/ and i386/, this approach reduced the repetition. This is first of three patches for Hyper-V enablement.
