rockchip/rk3399: Add Type-C PHY init

Though we don't use Type-C PHY to support USB3 in firmware,
we still need to initialize the Type-C PHY, and make sure
the power state of pipe is always fixed to U2/P2. After
this, we can force USB3 controller to work in USB2 only
mode stability.

BRANCH=none
BUG=chrome-os-partner:56425
TEST=Go to recovery mode, plug a Type-C USB drive containing
chrome OS image into both ports in all orientations, check if
system can boot form USB.
