hyperv: Clean up and fix the guest ID comment in hvgdk.h

Change the "64 bit" to "64-bit", and the "Os" to "OS".

Remove the obsolete paragraph since the guideline has been
published in the Hypervisor Top Level Functional Specification
for many years.

The "OS Type" is 0x1 for Linux, not 0x100.

No functional change.
