Enable special debug instrumentation analyze SDMMC data transfers.

This logic is as non-invasive as possible: It samples SDMMC

registers at key points in the data transfer and then dumps all of
|

the registers at the end of the transfer. If DEBUG_DMA is also
|

enabled, then DMA register will be collected as well. Requires also
