soc/mediatek/mt8188: Add DRAM fast calibration support
Define fields of sdram_params and enable MEDIATEK_BLOB_FAST_INIT to
run fast calibration for MT8188 using blob.
DRAM fast calibration logs:
DRAM-K: Fast calibration passed in 19530 msecs
dram size (romstage): 0x200000000
TEST=Fast calibration pass.
BUG=b:233720142
