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.
