MLK-16087 imx8qm/qxp: Disable kernel FDT nodes for the resources are not owned

Before starting the kernel, need to check if the enabled nodes (resources) in FDT
are owned by current partition.  If it is not owned, need to disable it because A core
can't access it.
We use the node's power-domain property to get the PD node which has the SCFW resource
id in its reg property. Then we can check it with SCFW.
