While it is really unlikely that we are failing to get only one of the
channels... It means anyway that the omap_hsmmc is not usable, but we will
still try to get via legacy mode and there is a chance that we might get some
channel.

Too bad that I can not send the conversion to dma_request_chan() yet due to
missing things in arch...

It might be simpler to just remove the printout of the rx/tx_req from the
dev_err() when reporting failed channel requests...

Fine with me too, I'll send that patch as well and let Ulf pick.
