Subject: [PATCH 1/9] dt-bindings: remoteproc: imx_rproc: support i.MX8QXP

From: Peng Fan <peng.fan@....com>

Add i.MX8QXP compatible

Add a new property rsrc-id for SoC which supports SCFW. This rsrc-id
is used to check whether remote process is under control of Linux or
not.

To i.MX8QM/QXP, when M4 is in the same hardware partition with Cortex-A
cores, need power up M4 through SCFW, then M4 could start. So introduce
power-domains property
