We will have the wl1251 defined as a child node of the mmc interface
and can read setup for gpios, interrupts and the ti,use-eeprom
property from there instead of pdata to be provided by pdata-quirks.

Fixes: 81eef6ca9201 ("mmc: omap_hsmmc: Use dma_request_chan() for requesting DMA channel")

This isn't needed as it seems. Perhaps remove or keep it as optional?
