Pandora_wl1251_init_card was used to do special pdata based setup of the sdio mmc interface. This does no longer work with v4.7 and later. A fix requires a device tree based mmc3 setup.

Therefore we move the special setup to omap_hsmmc.c instead of calling some pdata supplied init_card function.

The new code checks for a DT child node compatible to wl1251 so it will not affect other MMC3 use cases.

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