Current dsp node was configured with SOF in mind but it doesn't work well with imx8mp-evk dts. SOF controls audio IPs from firmware side while imx8mp-evk preffers to control audio IPs from Linux side. So, configure 'dsp' node to be used with rproc scenario and later will add a separate dts or an overlay to configure the node for SOF. This patch series configures and enables dsp node to be used with rproc. Changes since v1: - document syscon compatible as pointed by Peng Fan - do not disable dsp_reserved node in the dtsi file as pointed by Ahmad Fatoum.
