da8xx driver is registering and using the cppi dma controller but actually,
the da8xx has a cppi41 dma controller.
Update the driver to register and use the cppi41 dma controller.

Grr, MUSB_DMA_CPPI is certainly wrong! There's no CPPI 3.0 support for
DA8xx. Where have this come from?

Likewise, WTF?
I suggest that you fix this crap in a separate commit, to be backported
to -stable if needed.
Probably came from my DMA patch 7f6283ed6fe8 ("usb: musb: Set up function
Too bad I missed it back then. Then certainly this should be fixed in a
separate patch. The first hunk was not a part of that commit, tho...
pointers for DMA"). At that point I thought da8xxx.c and davinci.c are just
separate attempts of the same driver.. Sorry the number of musb glue layers
is just too confusing.
