The tcpc power domain will try to power up/down the power of Type-C PHY.
Hence, we need control it in Type-C PHY driver with the pm_runtime helper.

applied to my dts64 branch for 4.9 (or 4.10) after fixing the subject 
(rockchip: instead of rk3399:), as even without the advanced logic from patch1 
the driver core will already make sure to at least powerup the domain before 
probe and power-down after remove.
