Finish separating the HSMMC setup from the OMAP2 setup, then the
HSMMC stuff will be a lot easier to cope with. The HSMMC stuff
is never used with the mfd/menelaus transceiver/slot switch stuff;
including those data structures caused lots of hassles.

The only real issue with the HSMMC stuff is that it's got to continue
working with the many wiring options now in use.

Simplest to borrow a Beagle. Make sure whatever you do
can handle both standard SDHC cards, and also 8-bit HSMMC.
Once that works, the rest will fall out pretty easily.
