[PATCH 2/5] arm64: dts: imx8qxp: configure dsp node for rproc usage

From: Laurentiu Mihalcea <laurentiu.mihalcea@nxp.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.
