I imported patchset and started it on RockPro64. Enabled same config
options as on evb-rk3399. DeviceTree entries were already setup.

Pendrive in USB3 (type A) port gets recognized as SuperSpeed one (was
HighSpeed before). Type C port is not working - nevermind is it empty,
with usb-c pendrive plugged or with usb-c to usb-a/c/hdmi dongle with
usb-a pendrive.
