ramneek mehresh - Feb. 10, 2012, 10:36 a.m.
Add support for fixing usb mode and phy type for
MPH(Multi Port Host) USB controllers in device-tree nodes.
Required for socs like P3060, P5020, etc having MPH USB controller

Changes for v3:
	- removed const* type cast for node_type
	- used CONFIG_HAS_FSL_MPH_USB in condition for including
	  fdt_fixup_dr_usb()
