arm-bsp/u-boot: corstone1000: Change MMCOMM buffer location

Browse Source 
MM Communicate buffer is accessed by normal world but at the moment
it's allocated in the secure ram. This moves mm communicate buffer
to the DDR and also fixes the capsule buffer size since it cannot be
more than the bank size.
