[COMMUNITY] ADSP enable and add sound hardware abstraction in DT
The ADSP on Renesas SoCs required a reserved memory area to become enabled, and this needs to be done manually. This patch adds sound hardware abstraction information for the m3ulcb and m3ulcb-kf (kingfisher) device trees. This is helpful on-board the ADSP for dynamically determining sound hardware at runtime, allowing single binaries to be used between the two boards. Future work will incorporate the h3ulcb and Salvator boards into the abstraction.
