scripts/config_whitelist.txt should be updated to remove the non-DM version macros: CONFIG_MMC_SPI_xxx
cmd/mmc_spi.c should be completely dropped as it is for non-DM version MMC SPI driver.
mmc_spi_init() declaration in mmc.h should be removed.
With commit: f51d7fc8ce455ef201f86e1fab4d380444b96789 ("board: Arcturus: DM: Disable drivers without DM support"), UCP1020 board removes most legacy non-DM SPI MMC support, but still has CONFIG_MMC_SPI in UCP1020.h. That should be removed too. +Oleksandr Zhadan and Michael Durrant who maintains UCP1020 board for the awareness.
