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.

Does not look like a generic property, so please add vendor prefix.
Suffix also would look good, so:
