[RFC PATCH v1 1/9] net: phy: micrel: move phy reg offsets to common header

From: Oleksij Rempel
Date: Wed May 05 2021 - 05:22:56 EST

From: Michael Grzeschik <m.grzeschik@xxxxxxxxxxxxxx>

Some micrel devices share the same phy register defines. This patch
moves them to one common header so other drivers can reuse them.
