soc/mediatek/mt8186: Support DRAM fast calibration using blob

For most MediaTek SoCs (MT8183, MT8192, MT8195) we rely on an external
program (e.g., the "DRAM blob") to do the full DRAM calibration first,
then store and and apply the generated parameters to the reference
"fast DRAM calibration" in the vendor/mediatek folder for normal system
boot.

Starting with MT8186, the "DRAM blob" will also support fast calibration
so both first boot and normal boot can follow the same path for DRAM
calibration.
