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.

The DRAM initialization will keep and return DRAM information (size,

geometry and other DDR info) so we can fill that into the CBMEM.
