Subject: [PATCH v2 03/14] ARM: dts: imx6ull-colibri: add phy-supply to fec

From: Philippe Schenker <philippe.schenker@...adex.com>

This adds the proper phy-supply to the FEC. This supply is actually
switched by a clock that is now properly stated. This has the advantage
to add a delay for that particular regulator which is needed.
