REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3966

This patch series is a follow up of previous submission:
https://edk2.groups.io/g/devel/message/91075

v2 patch changes include feedback for v1 series:
a. Removed PCD replacement related code change;

>From PI Specification v1.7 Errata A, EFI_PERIPHERAL_DOCKING is defined as
0xD0000 (as well as included in PiStatusCode.h).

However, subclass employed as PCD for TPM peripheral in SecurityPkg is
also defined as 0xD0000. The TPM subclass code was used in TcgPei.c when
reporting error codes.

The collision of subclass definition could cause the parsing of reported
errors being ambiguous.

This patch series add EFI_PERIPHERAL_TPM as a spec-defined value and
removed potential usages in the SecurityPkg.
