ARM: 6445/1: fixup TCM memory types

After Santosh's fixup of the generic MT_MEMORY and
MT_MEMORY_NONCACHED I add this fix to the TCM memory types.
The main change is that the ITCM memory is L_PTE_WRITE and
DOMAIN_KERNEL which works just fine. The changed to the DTCM
is just cosmetic to fit with surrounding code.
