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.
