Memory map remapping is a platform specific feature only enabled by some platforms. Instead of keeping this function empty for most platforms, the function has been removed. This feature can easily fit in any other ArmPlatformLib function. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@12632 6f19259b-4bc3-4df7-8a09-765794883524
