  1. rtos: branch out dma.h for Zephyr and XTOS 

    The SOF DMA RTOS interface is one of the largest and also one of the
hardest to maintain, as it's used a lot in SOF, and there is unfortunate
overlap in interface naming between Zephyr and XTOS.

To get the cleanup work started, branch out the sof/lib/dma.h for Zephyr
and remove the conditional definitions from both versions. This patch
maintains support for all build variants, including building SOF with
Zephyr but using XTOS drivers.

  2. zephyr: sof/lib/dma: add inline documentation to dma.h 

    Add a note to Zephyr sof/lib/dma.h explaining the relation of
SOF and Zephyr DMA interfaces and warn about the name space overlaps
that exist. Also enumerate the main usage scenarios that have
to be handled in this file.
