Subject: [edk2] [PATCH v2] MdeModulePkg: Remove PcdIdentifyMappingPageTablePtr

PcdIdentifyMappingPageTablePtr was used to share page table buffer between modules.
Buf after some changes on 2015/07/17, it was useless and could be removed.
https://bugzilla.tianocore.org/show_bug.cgi?id=1304

v2:
1.Remove PcdIdentifyMappingPageTablePtr in MdeModulePkg.uni.
2.Update the commit message.
