[PATCH v3 2/6] arm64: dts: imx8-ss-audio: configure dsp node for rproc usage

From: Laurentiu Mihalcea <laurentiu.mihalcea at nxp.com>

The 'dsp' node is currently configured for running an
audio firmware. Since the firmware requires that some
audio-related IPs be disabled in Linux, this will clash
with the configurations from the imx8 board DTs
(i.e: imx8qm-mek, imx8qxp-mek, etc...), thus making the
dsp unusable (since the firmware won't function properly).

To avoid this issue, configure the 'dsp' node for rproc.
This way, users will be able to use the dsp alongside the
board-level audio configuration as long as the firmware
doesn't need the audio IPs.
