[PATCH v3 01/12] mmc: fsl_esdhc_imx: make BLK as hard requirement of DM_MMC

[Sean Anderson]

[ fsl_esdhc commit 41dec2fe99512e941261594f522b2e7d485c314b ]

U-boot prefers DM_MMC + BLK for MMC. Now eSDHC driver has already
support it, so let's force to use it.

- Drop non-BLK support for DM_MMC introduced by below patch.
  66fa035 mmc: fsl_esdhc: fix probe issue without CONFIG_BLK enabled

- Support only DM_MMC + BLK (assuming BLK is always enabled for DM_MMC).

- Use DM_MMC instead of BLK for conditional compile.

Changes in v3:
- Drop Kconfig BLK dependency
