Subject: [PATCH V2 3/5] phy: bcm-ns-usb3: enable MDIO in the platform specific code

From: Rafał Miłecki <rafal@...ecki.pl>

When we finally start using MDIO layer then bus initialization will be
handled in a separated driver. It means our code handling this has to be
used for the platform driver only.
