This is so wrong. You are registering one kind of usb phy driver from
an other. Change drivers/usb/phy/ulpi.c to be a platform device. The
whole flag system in it is pretty horrid. While you are at it, change
that so it sets the values based on boolean flags from OF properties
or platform data.

NAK for the whole set.
