Try:
make O=build dt_binding_check DT_SCHEMA_FILES=net/pcs/altr,gmii-to-sgmii.yaml

The full path should work, but seems there is some issue. But really, 
DT_SCHEMA_FILES is just a sub-string to match with schema $id.

'reg' should be the number of logical entries (and what they are), not 
the number of cells.
