I got my hands on a AM18x WL12xx module so I could test MMC1 and this
exposed some bugs in the driver's handling of the second EDMA controller
case. DA850/OMAP-L138/AM1x have this second EDMA controller. I've
addressed this in v2 which will be posted shortly.

I'm expecting to receive a DM646x EVM RSN so I can cover testing that
part as well.
