[PATCH V2 1/6] dt-bindings: remoteproc: imx_rproc: support i.MX8QXP

From: Peng Fan (OSS)

From: Peng Fan <peng.fan@xxxxxxx>

Add i.MX8QXP compatible

Add a new property rsrc-id(resource id) for SoC which supports
SCFW(System Controller Firmware). SCFW manages resources using resource
id, here the 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.
