2014-30-24: DMA is not currently functional and without DMA, there
may not be reliable data transfers at high speeds due
to data overrun problems. The current HSMCI driver
supports DMA via the DMAC. However, the data sheet
only discusses PDC-based HSMCI DMA (although there is
a DMA channel interface definition for HSMCI). So
this is effort is dead-in-the-water for now.
