commit 4f9007d692017cef38baf2a9b82b7879d5b2407b upstream.
Since v4.7 the dma initialization requires that there is a device tree property for "rx" and "tx" channels which is not provided by the pdata-quirks initialization.
By conversion of the mmc3 setup to device tree this will finally allows to remove the OpenPandora wlan specific omap3 data-quirks.
