USB: core: add USB_QUIRK_NO_LPM for VIA Labs USB 2.0 hub

The VIA Labs, Inc. USB 2.0 hub controller (2109:2817),
found in a KVM switch, fails to enumerate high-power devices during
cold boot and system restart.

Applying the kernel parameter
  usbcore.quirks=2109:2817:k
resolves the issue.

Enumeration failure log:
  usb 1-1.2.3: device descriptor read/64, error -32
  usb 1-1.2.3: Device not responding to setup address.
  usb 1-1.2.3: device not accepting address 11, error -71
  usb 1-1.2-port3: unable to enumerate USB device

Add USB_QUIRK_NO_LPM for this device.
