OK. The sdio_irq should be just set in struct omap_hsmmc_host instead.

Great. How about make the pbias driver DT only? Let's not touch the board-*.c
files any longer as those will be going away for v3.14. We can probably keep
the old callback support in place also, and then remove it for v3.15.

And after that it would certainly make sense to rip out the platform data
fomr hsmmc driver just to get rid of the legacy support for multiplexing slots
that's not needed in this driver. That would allow replacing all mmc->slots[0]
accesses with something more standard.
