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. Generally, this code was and still is a hack and should be moved to mmc core to e.g. read such properties from optional DT child nodes.
