porting guide: update mandated platform settings

Generic code expects platform sets TZDRAM_BASE, TZDRAM_SIZE,
TEE_RAM_START, TEE_RAM_VA_SIZE, TA_RAM_START, TA_RAM_SIZE,
TEE_SHMEM_START, TEE_SHMEM_SIZE and TEE_LOAD_ADDR.

Generic code with pager enable expects also TZSRAM_BASE, TZSRAM_SIZE
and TEE_RAM_PH_SIZE.

DRAM0_BASE/SIZE is not required by the generic code.
