Subject: [PATCH v2 2/4] net: mvmdio: allow up to four clocks to be specified for orion-mdio

From: Josua Mayer <josua@...id-run.com>

Allow up to four clocks to be specified and enabled for the orion-mdio
interface, which are required by the Armada 8k and defined in
armada-cp110.dtsi.

Fixes a hang in probing the mvmdio driver that was encountered on the
Clearfog GT 8K with all drivers built as modules, but also affects other
boards such as the MacchiatoBIN.
