1, PeiPcdLib use EFI_PEI_PCD_PPI defined in PI 1.2 to handle dynamicEx type PCD request.
2, DxePcdLib use EFI_PCD_PROTOCOL defined in PI 1.2 to handle dynamicEx type PCD request.
3, There is no change for dynamic type PCD.
4, Refine the INF's comments.

# Instance of PCD Library using PCD Protocol.
#
-# PCD Library that uses the PCD Protocol to access Dynamic and DynamicEx PCD entries.
+# There are two PCD PPIs as follows:
+# 1) PCD_PROTOCOL
+# It is EDKII implementation which support Dynamic/DynamicEx Pcds.
+# 2) EFI_PCD_PROTOCOL
+# It is defined by PI specification 1.2, Vol 3 which only support dynamicEx
+# type Pcd.
#
-# Copyright (c) 2007 - 2008, Intel Corporation.
+# For dynamicEx type PCD, it is compatible between PCD_PROTOCOL and EFI_PCD_PROTOCOL.
+#
+# This library instance uses the PCD_PROTOCOL to handle dynamic PCD request and use
+# EFI_PCD_PROTOCOL to handle dynamicEx type PCD.
