ARM: OMAP2+: Provide alias to USB PHY clocktracking-omap-fixes-13.06-ll-20130723.0tracking-omap-fixes-13.06-ll-20130717.0tracking-omap-fixes-13.06-ll-20130711.0tracking-omap-fixes-13.06-ll-20130705.0tracking-omap-fixes-13.06-ll-20130703.0tracking-omap-fixes-13.06-ll-20130621.0tracking-omap-fixes-13.06-ll-20130620.1
Till the OMAP clocks are correctly defined in device tree, use
this temporary hack to provide clock alias to the USB PHY clocks.
Without this, USB Host & Ethernet will not be functional with
device tree boots on Panda and uEVM.
