ArmVirtPkg: Disable the TPM2 platform hierarchy
Disable the TPM2 platform hierarchy by directly calling
ConfigureTpmPlatformHierarchy().
Per the TCG firmware specification "TCG PC Client Platform Firmware Profile
Specification" the TPM 2 platform hierarchy needs to be disabled or a
random password set and discarded before the firmware passes control to the
next stage bootloader or kernel.
Current specs are here:
https://trustedcomputinggroup.org/wp-content/uploads/TCG_PCClient_PFP_r1p05_v23_pub.pdf
Section 11 states:
"Platform Firmware MUST protect access to the Platform Hierarchy
and prevent access to the platform hierarchy by non-manufacturer-
controlled components."
