soc/mediatek: Add `MEDIATEK_DRAM_ADAPTIVE` config to support dram adaptive
Starting from MT8195, MediaTek platform supports "dram adaptive" to
automatically detect dram information, including channel, rank, die
size..., and can automatically configure EMI settings. So we can just
pass a placeholder param blob to `mt_mem_init_run` by enabling this
option.
Platforms (MT8173, MT8183, MT8192) which do not support "dram adaptive"
need to implement `get_sdram_config` to get onboard DRAM configuration
info.
TEST=emerge-geralt coreboot && emerge-asurada coreboot
TEST=CONFIG_MEDIATEK_DRAM_ADAPTIVE is set to y on geralt
TEST=CONFIG_MEDIATEK_DRAM_ADAPTIVE is no set on asurada
