mediatek: Map SRAM as secure and cached memory
This patch changes the mapping of SRAM from non-secure to secure. Without this patch, mmu_config_range() can not work when MMU is enabled. The new config is still in non-secure cache since TTB section is allocated in SRAM which is mapped as non-secure.
