hv: tpm2: do tpm2 fixup for security vm

Browse Source 
ACRN used to prepare the vTPM2 ACPI Table for pre-launched VM at the build stage
using config tools. This is OK if the TPM2 ACPI Table never changes. However,
TPM2 ACPI Table may be changed in some conditions: change BIOS configuration or
update BIOS.

This patch do TPM2 fixup to update the vTPM2 ACPI Table and TPM2 MMIO resource
configuration according to the physical TPM2 ACPI Table.
