Subject: [PATCH v2 3/6] arm64: dts: imx8qxp: configure dsp node for rproc usage

From: Laurentiu Mihalcea <laurentiu.mihalcea@....com>

Currently, the dsp node is configured for SOF usage, which is not the
"default" case and should be done in a separate SOF DTS. As such,
configure the dsp node for rproc usage, which is the "default" case.

This also includes the addition of the 2 optional power domains which
may be required by some applications.
