Until commit fa2d0aa96941 ("mmc: core: Allow setting slot index via
device tree alias") was introduced, our usdhc3 and usdhc4 devices
were enumerated as mmc0 and mmc1. The mmc1 device is used to boot/update
the board and its name must be fixed.

With the referenced commit, aliases from imx6qdl.dtsi took effect.
Override the aliases to get back the original device indexes.
