Add a PHY provider driver for the rk3399 SoC Type-c PHY. The USB
Type-C PHY is designed to support the USB3 and DP applications. The
PHY basically has two main components: USB3 and DisplyPort. USB3
operates in SuperSpeed mode and the DP can operate at RBR, HBR and
HBR2 data rates.

Changes in v6:
- delete the support of PIN_ASSIGN_A/B
- set the default mode to MODE_DFP_USB
- disable DP PLL at USB3 only mode

Changes in v5:
- support get property from extcon
- remove PIN ASSIGN A/B support

Changes in v4:
- select EXTCON
- use phy framework to control the USB3 and DP function
- rename PIN_MAP_ to PIN_ASSIGN_

Changes in v3:
- remove the phy framework(Kishon Vijay Abraham I)
- add parentheses around the macro
- use a single space between type and name
- add spaces after opening and before closing braces.
- use u16 for register value
- remove type-c phy header file
- CodingStyle optimization
- use some cable extcon to get type-c port information
- add a extcon to notify Display Port

Changes in v2:
- select RESET_CONTROLLER
- alphabetic order
- modify some spelling mistakes
- make mode cleaner
- use bool for enable/disable
- check all of the return value
- return a better err number
- use more readx_poll_timeout()
- clk_disable_unprepare(tcphy->clk_ref);
- remove unuse functions, rockchip_typec_phy_power_on/off
- remove unnecessary typecast from void *
- use dts node to distinguish between phys.

Changes in v1:
- update the licence note
- init core clock to 50MHz
- use extcon API
- remove unused global
- add some comments for magic num
- change usleep_range(1000, 2000) tousleep_range(1000, 1050)
- remove __func__ from dev_err
- return err number when get clk failed
- remove ADDR_ADJ define
- use devm_clk_get(&pdev->dev, "tcpdcore")
