phy: rockchip-inno-usb2: support otg-port for rk3399
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

functions:
- Support BC1.2 charger detect, and use extcon notifier to
send USB charger types to power driver.
- Support PHY suspend for power management.
- Support OTG Host only mode.
