dt-bindings: ethernet-controller: fix fixed-link specification

stable inclusion
from stable-5.10.21
commit 33dbc6759de36ce6c95e1d2d325e663b87e13ef0
bugzilla: 50609

--------------------------------

commit 322322d1 upstream.

The original fixed-link.txt allowed a pause property for fixed link.
This has been missed in the conversion to yaml format.
