Subject: [RFC PATCH 2/2] ARM: dts: imx6ull: 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 adds the
advantage to add a delay for that particular regulator that is needed.

Signed-off-by: Philippe Schenker <philippe.schenker@...adex.com>
