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.
