Subject: [PATCH 0/3] Reset USB3 controller before initializing Type-C PHY on rk3399

This series adds USB3 OTG controller reset for rk3399 Type-C PHY, and use the
reset to hold the whole USB3 OTG controller in reset state to keep the PIPE
power state in P2 before initializing Type-C PHY, it's useful to avoid waiting
for PHY PMA and PIPE ready timeout.
