u-boot is trying to make CONFIG_BLK as a hard requirement for DM_MMC. But now it's still not.
config BLK bool "Support block devices" depends on DM default y if DM_MMC
When fsl_esdhc driver was reworked for DM_MMC support, DM_MMC without CONFIG_BLK enabled wasn't considered. This patch is to fix probe issue without CONFIG_BLK enabled.
