[PATCH v1 1/5] dt-bindings: net: Add HPE GXP UMAC MDIO

[nick.hawkins@hpe.com]

From: Nick Hawkins <nick.hawkins@hpe.com>

Provide access to the register regions and interrupt for Universal
MAC(UMAC). The driver under the hpe,gxp-umac-mdio will provide an
interface for managing both the internal and external PHYs.
