The rk3399 SoC USB2 PHY is comprised of one Host port and
one OTG port. And OTG port is for USB2.0 part of USB3.0 OTG
controller, as a part to construct a fully feature Type-C
subsystem.

functions:

  send USB charger types to power driver.
- Support PHY suspend for power management.
- Support OTG Host only mode.
