phy: rockchip: add usbdp combo phy driver
This adds a new USBDP combo PHY with Samsung IP block driver.
The driver get lane mux and mapping info in 2 ways, supporting
DisplayPort alternate mode or parsing from DT. When parsing from DT,
the property "rockchip,dp-lane-mux" provide the DP mux and mapping
info. This is needed when the PHY is not used with TypeC Alt-Mode.
For example if the USB3 interface of the PHY is connected to a USB
Type A connector and the DP interface is connected to a DisplayPort
connector.
When do DP link training, need to set lane number, link rate, swing,
and pre-emphasis via PHY configure interface.
