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 v2:
- used compat_dr and compat_mph strings instead of
compat[] array
- removed unrelated changes/fixes(which are sent in a separate patch)
