mx6slevk_spl_defconfig does not have CONFIG_DM_MMC selected and it is
also broken since 2017.05 due to this commit:

    imx: mx6slevk: enable more DM drivers

    Enable more DM drivers. The imx I2C/MMC DM drivers needs DM_GPIO
    enabled. So needs to enable them together.

    DM FEC and SPI are not enabled, but they use gpio in board code.
    So use gpio_request first to request the gpio, because DM_GPIO
    is enabled.

I managed to fix it and will submit a fix for it.

mx6slevk_defconfig which has CONFIG_DM_MMC=y is still broken though
and not sure how to fix it.
