Move the DMA channel used in cyclic mode (audio) to the highest priority
event queue which helps to reduce audio problems.
When the channel is terminated, move it back to the default queue.

Hi,
It is preferred that audio is served with the highest priority queue in order to
avoid delays in data transfer between memory and audio IP.
The following series will add an API to arch code to assign a channel to a given
queue.
The default queue is changed from 0 (highest priority) to lowest
Use the lowest priority queue as default for clients.

In some cases it is desired to move a channel to a specific event queue.
Such a use case is audio, where it is preferred that it is served with
highest priority compared to other DMA clients.
