soc/mediatek/mt8196: Add dram calibration support

Add support for MT8196 DRAM calibration. DRAM parameters and related
constants are added in dramc_param.h and dramc_soc.h. As MT8196's
dramc_param struct size is different from other MediaTek SoCs,
replace the hardcoded RW_MRC_CACHE size in common code with a constant
derived from chromeos.fmd.

The common emi.c can be reused for MT8196 as well, so remove the
duplicate mt8196/emi.{c,h}.

Enable MEDIATEK_DRAM_BLOB_FAST_INIT to allow running DRAM fast
calibration via the DRAM blob.
