With the callback implemented omap-dma can provide information to client
drivers regarding to supported address widths, directions, residue
granularity, etc.

prep_slave_sg and prep_dma_cyclic callbacks have mostly same failure cases
with the same texts printed in case we hit them. It helps when debugging if
we know exactly which callback generated the errors.
At the same time change the debug level for descriptor allocation failure
from dbg to err
Remove the dai startup callback and do the dma_data setup for dmaengine
in the dai_probe function.

In case of not supported direction it is better to print the direction also.
It is unlikely, but in such an event it helps with the debugging.

We need to place constraint on the period size (and indirectly to buffer
size) if the read or write AFIFO is enabled and it is configured for more
than one word otherwise the DMA will fail in buffer configuration where
the sizes are not aligned with the requested FIFO configuration.
