Fix crash in UnixPkg and BeagleBoard caused by gSmmBase2 getting added to the now incorectly named mARchProtocols list. CoreDispatchMissingArchProtocols() did to check to see if the element was an AP (not all are now). Also Missing entry was not bounds checked, it was assumed to be <= Index witch is no longer true. So in both UnixPkg and BeagleBoard the loop was blowing past the end and garbage data caused page faults. Also add m prefix to global.
