soc/mediatek: Add a configurate "USE_CBMEM_DRAM_INFO"
The memory initialization reference code didn't support returning
DRAM information in the old platforms, for example MT8192 and MT8195.
So we have to add a new configuration USE_CBMEM_DRAM_INFO to make
sure the common code will try to get DRAM information on new
platforms supporting that.
BUG=none
TEST=build pass
