[edk2-platforms][PATCH v2 0/4] MinPlatformPkg: Add TPM platform hier disable support

["Michael Kubacki" <mikuback@linux.microsoft.com>]

From: Michael Kubacki <michael.kubacki@microsoft.com>

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3411

This patch series adds support in TpmPlatformHierarchyLib to either
randomize the platform auth (current behavior) or disable the
platform auth (new behavior) based on a new PCD introduced to
MinPlatformPkg: PcdRandomizePlatformHierarchy.

Some platforms that would like to adopt MinPlatformPkg prefer to
disable the platform hierarchy as opposed to the randomization
approach.

Minor changes are included to eliminate code duplication in impacted
code.

V2 changes:
1. Update code that randomizes the platform auth in Tcg2PlatformPei
   to use the TpmPlatformHierarchyLib interface for platform
   hierarchy configuration.
2. Remove pre-existing redundant code in Tcg2PlatformPei.
3. Add a PCD to allow the platform integrator to choose how to
   configure the TPM platform hierarchy.
