Apparently, our earlier assumption that the BROM will always set up the iomux for SDcard communication does not always hold true: when booting U-Boot from the on-module (on the RK3368-uQ7) eMMC, the SDcard pins are not set up and need to be configured by the pinctrl driver to allow SD card access.
This change implements support for setting up the SDMMC pins in pinctrl for the RK3368.
