To i.MX8M Family variants, fec maybe fused out. Bootloader could use
this property to read out the fuse value and mark the node status
at runtime.

Running 'make dtbs_check' with the schema in this patch gives the
following warnings. Consider if they are expected or the schema is
incorrect. These may not be new warnings.

Note that it is not yet a requirement to have 0 warnings for dtbs_check.
This will change in the future.
