Igor Grinberg 13dd0c9767 USB: otg/ulpi: extend the generic ulpi driver. 
1) Introduce ulpi specific flags for control of the ulpi phy
2) Extend the generic ulpi driver with support for Function and
Interface control of upli phy
3) Update the platforms using the generic ulpi driver with new ulpi
flags
4) Remove the otg control flags not in use
