Ajay Kaher a2ab25529b x86/vmware: Parse MP tables for SEV-SNP enabled guests under VMware hypervisors ...

Under VMware hypervisors, SEV-SNP enabled VMs are fundamentally able to boot
without UEFI, but this regressed a year ago due to:

  0f4a1e8098 ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests")

In this case, mpparse_find_mptable() has to be called to parse MP
tables which contains the necessary boot information.

[ mingo: Updated the changelog. ]

Fixes: 0f4a1e8098 ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests")
