The generate_guest_id function is more suitable for use after the
following modifications.
1. The return value of the function is modified to u64.
2. Remove the d_info1 and d_info2 parameters from the function, keep the
u64 type kernel_version parameter.
3. Rename the function to make it clearly a Hyper-V related function,
and modify it to hv_generate_guest_id.

Add ARM64-specific code to initialize the Hyper-V
hypervisor when booting as a guest VM.
This code is built only when CONFIG_HYPERV is enabled.

hyperv-tlfs.h defines Hyper-V interfaces from the Hyper-V Top Level
Functional Spec (TLFS), and #includes the architecture-independent
part of hyperv-tlfs.h in include/asm-generic. The published TLFS
is distinctly oriented to x86/x64, so the ARM64-specific
hyperv-tlfs.h includes information for ARM64 that is not yet formally
published. The TLFS is available here:
docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/tlfs
mshyperv.h defines Linux-specific structures and routines for
interacting with Hyper-V on ARM64, and #includes the architecture-
independent part of mshyperv.h in include/asm-generic.
Use these definitions to provide utility functions to make
Hyper-V hypercalls and to get and set Hyper-V provided
registers associated with a virtual processor.
