[PATCH 1/2] ARM: dts: imx51-babbage: Fix USB PHY duplicate unit-address

From: Fabio Estevam <fabio.estevam at nxp.com>

Currently the following DTC warning is seen with W=1:

arch/arm/boot/dts/imx51-babbage.dtb: Warning (unique_unit_address): /usbphy/usbphy at 0: duplicate unit-address (also used in node /usbphy/usbh1phy at 0)

Fix it by moving the USB PHY node outside of simple-bus and drop the
unneeded unit-address.
