Check in the Pcd service Driver/PEIM according to the new way of generating PCD Database
LIMITATION: 1) ONLY dynamic type PCD is supported for now. DynamicEx is not supported. 2) HII enable and VPD is not tested. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@253 6f19259b-4bc3-4df7-8a09-765794883524
