Rafael Aquini 6b6e0eef10 x86/vmware: Parse MP tables for SEV-SNP enabled guests under VMware hypervisors 
JIRA: https://issues.redhat.com/browse/RHEL-84184

This patch is a backport of the following upstream commit:
commit a2ab25529bbcea51b5e01dded79f45aeb94f644a
Author: Ajay Kaher <ajay.kaher@broadcom.com>
Date:   Thu Mar 13 17:31:11 2025 +0000

    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:

      0f4a1e80989a ("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: 0f4a1e80989a ("x86/sev: Skip ROM range scans and validation for SEV-SNP guests")
