ARM: dts: imx53-ard: add regulators for lan9220
commit 1eec0c569523782392b5e6245effddb626213b8c upstream.
Since commit c7e963f (net/smsc911x: Add regulator support), the lan9220
device tree probe fails on imx53-ard board, because the commit makes
VDD33A and VDDVARIO supplies mandatory for the driver.
Add a fixed dummy 3V3 supplying lan9220 to fix the regression.
