dt-bindings: remoteproc: imx_rproc: Support i.MX8QXP

Add i.MX8QXP compatible

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

Add fsl,entry-address to specify the entry address which used by SCFW
to kick M4.

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.
