USB: quirks: Add no-lpm quirk for Raydium touchscreens
Raydium USB touchscreen fails to set config if LPM is enabled:
[ 2.030658] usb 1-8: New USB device found, idVendor=2386, idProduct=3119
[ 2.030659] usb 1-8: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 2.030660] usb 1-8: Product: Raydium Touch System
[ 2.030661] usb 1-8: Manufacturer: Raydium Corporation
[ 7.132209] usb 1-8: can't set config #1, error -110
Same behavior can be observed on 2386:3114.
Raydium claims the touchscreen supports LPM under Windows, so I used
Microsoft USB Test Tools (MUTT) [1] to check its LPM status. MUTT shows
that the LPM doesn't work under Windows, either. So let's just disable LPM
for Raydium touchscreens.
