soc/mediatek: Enable DRAM scramble on fast calibration flow
No matter what DRAM calibration is performed, DRAM scramble should be
enabled as long as MEDIATEK_DRAM_SCRAMBLE is set to y. Currently, DRAM
scramble is enabled only if full calibration is performed. Correct the
behavior by adding DRAMC_CONFIG_SCRAMBLE to the header config in fast
calibration flow.
BUG=b:285474337
TEST=Check the scramble feature is disabled on serial build
