Hi,
Changes since v2:
- Dropped patch 10 from v2 (simplify direction configuration...)
- Dropped the channel priority related patches since we are going to go via
different route for configuring the priority.
- Added ACK from Joel for the patches since they are not changed since v2
Changes
For later use save the number of queues available for the CC.

Pause/Resume can be used by the audio stack when the stream is paused/resumed
The edma platform code has support for this and the legacy audio stack used
this.

The edmacc_param struct should follow the layout of the paRAM area in the
HW. Be explicit on the size of the fields (u32) and also mark the struct
as packed to avoid any padding on non 32bit architectures.

When clients asks for maxburst = 0 it is basically the same case as if they
were asking for maxburst = 1 since in both case ASYNC need to be used and
the eDMA is expected to write/read one word per DMA request.

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.

It helps to identify issues if we have some information regarding to the

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
