usb: add quirks for Lenovo OneLink+ Dock
The Lenovo OneLink+ Dock contains two VL812 USB3.0 controllers:
17ef:1018 upstream
17ef:1019 downstream
Those two controllers both have problems with some USB3.0 devices,
particularly self-powered ones. Typical error messages include:
Timeout while waiting for setup device command
device not accepting address X, error -62
unable to enumerate USB device
By process of elimination the controllers themselves were identified as
the cause of the problem. Through trial and error the issue was solved
by using USB_QUIRK_RESET_RESUME for both chips.
