Subject: [RFC PATCH 0/3] Add APIs to request TX/RX DMA channels by ID

The existing APIs for requesting TX and RX DMA channels rely on parsing
a device-tree node to obtain the Channel/Thread IDs from their names.
However, it is possible to know the thread IDs by alternative means such
as being informed by Firmware on a remote core regarding the allocated
TX/RX DMA channel IDs. Thus, add APIs to support such use cases.

Series is based on linux-next tagged next-20231110.
