[ Upstream commit 2398c41d64321e62af54424fd399964f3d48cdc2 ]
With a wl1251 child node of mmc3 in the device tree decoded in omap_hsmmc.c to handle special wl1251 initialization, we do no longer need to instantiate the mmc3 through pdata quirks.
We also can remove the wlan regulator and reset/interrupt definitions and do them through device tree.
