[PATCH 2/2] arm64: dts: imx8mp: add reserve-memory nodes for DSP

["Iuliana Prodan (OSS)" <iuliana.prodan@xxxxxxxxxxx>]

From: Iuliana Prodan <iuliana.prodan@xxxxxxx>

Add the reserve-memory nodes used by DSP when the rpmsg
feature is enabled.
These can be later used in a dsp node, like:
dsp: dsp@3b6e8000 {
	compatible = "fsl,imx8mp-dsp";
	reg = <0x3b6e8000 0x88000>;
	mbox-names = "tx0", "rx0", "rxdb0";
	mboxes = <&mu2 2 0>, <&mu2 2 1>,
		<&mu2 3 0>, <&mu2 3 1>;
	memory-region = <&dsp_vdev0buffer>, <&dsp_vdev0vring0>,
		<&dsp_vdev0vring1>, <&dsp_reserved>;
	status = "okay";
};
