As per USDHC boot eFUSE descriptions: USDHC3 => devno 2 USDHC4 => devno 3 Linux will detect mmc0, mmc1, mmc2 based on the status "okay" on usdhc so imx6qdl-icore-rqs.dtsi has enabled usdhc1, usdhc3 and usdhc4.But U-Boot can detect based on the aliases so add mmc1, mmc2 for usdhc3 and usdhc4 respectively and return the board_mmc_get_env_dev by subtracting -1 Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>
