As documented in 90bdf1e5d1e4 ("mci: dw_mmc: match against StarFive MMC
compatibles"), it was intended for the reset to remain optional as to
not break existing users. Unfortunately, my later a3cf324593ea
("mci: dw_mmc: add optional reset line") didn't heed that and made it
required, breaking SoCFPGA DW-MMC use as a result.

Revert that line to fix the regression.
