commit e58e68d9 ("mmc: mtk-sd: assign plat->cfg.f_max with a correct value") wrongly assumed that plat->cfg.f_max is always unset at the time mscd_drv_probe() is run. This is not true in case max-frequency being defined in device tree, as it is then already set by mmc_of_parse() in msdc_of_to_plat(). Only set plat->cfg.f_max to the default maximum value in case it is not already set to a sane value.
