phy: add NXP PTN3222 eUSB2 to USB2 redriver

The NXP PTN3222 is the single-port eUSB2 to USB2 redriver that performs
translation between eUSB2 and USB2 signalling schemes. It supports all
three data rates: Low Speed, Full Speed and High Speed.

The reset state enables autonegotiation of the PHY role and of the data
rate, so no additional programming is required.
