ARM: dts: imx53-ard: add regulators for lan9220
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. Cc: stable@vger.kernel.org Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
