  1. drivers: dma: Add initial support for NXP SDMA 

    This adds initial support for NXP SDMA controller. We make use
of NXP HAL to configure the IP.

SDMA uses BD (buffer descriptors) to describe a transfer. We create
a cyclic list of descriptors and trigger them manually at start and
later when data is available.

This is tested using Sound Open Firmware app on top of Zephyr.
