I've applied a slightly different variant in [0] with your commit message and
moved the dma properties to the mmc/emmc nodes in rk3xxx.dtsi - as the dma
channels are the same on both rk3188 and rk3066.

While at it, I've also added the sdio dma as there is no need to leave it out.

Also when changing the devicetree, please do not append stuff at the bottom
but instead sort new nodes (the &mmc &emmc in this case) and properties
alphabetically.

Thanks
Heiko
