[edk2-devel] [PATCH 16/19] DynamicTablesPkg: Move PCC Type2 info to Arch Common

["PierreGondois" <pierre.gondois@arm.com>]

From: Sami Mujawar <sami.mujawar@arm.com>

Move the PCC Subspace Type2 info object from Arm Namespace to
the Arch Common namespace.

Correspondingly also update the following modules to reflect the
changes introduced by the move:
 - PCCT generator
 - ConfigurationManagerObjectParser
 - Dynamic Plat Repo TokenFixer map.
