[PATCH v2 0/4] Cleanup dma device in spl and move dma channel[0]

Hi Prasanth,

> 1> Improve subject of commit.
> 2> Add warning on dma device not found.
> 3> Do channel allocation only for udma and bcdma. Passthrough for all other types.

Is there any reason why devices like j721e_beagleboneai64 and
m62x_beagleplay and other TI devices aren't changed as part of this
change?
