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

Signed-off-by: Ramneek Mehresh ramneek.mehresh@freescale.com --- Changes for v3: - removed const* type cast for node_type - used CONFIG_HAS_FSL_MPH_USB in condition for including fdt_fixup_dr_usb()
