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 implementation of fast calibration may need
to be changed, and a "DRAM blob" only path is introduced for devices
that have to do both full and fast calibration using the external blob.
TEST=fast calibration pass on kingler/krabby
