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.
BUG=b:80501386
TEST=Boots correctly on Kukui and Elm
