[SRU,C/D/Unstable,1/1] USB: quirks: Add no-lpm quirk for Raydium touchscreens

BugLink: https://bugs.launchpad.net/bugs/1802248

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.

Also applied to cosmic/master-next branch, removing the "linux-next"
part from the provenance.

Thanks,
