FSP/MDST: Fix TCE alignment issue
We have used TCE_MASK value (4095) instead of TCE_PSIZE (4096) to align memory
source address. In some corner cases (like source memory size = 4097) we may
endup doing wrong mapping and corrupting part of SYSDUMP.
This patch uses ALIGN_UP macro with TCE_PSIZE value for alignining memory.
