Bug description:
  [Impact]
  Some LG touchscreens reported themselves as generic touch devices,
  actually it is multitouch devices.
  Even after adding IDs in hid-multitouch, hid-generic will bind the device 
still.
  multitouch features are not supported.

  [Fix]
  commit e04a0442 make hid-generic work nicely with other drivers like 
hid-multitouch.
  If other drivers match the devices, hid-generic will step back.
  This patch will benefit many devices to support their own drivers without 
adding IDs.

  [Test]
  Verified on LG/ELAN/RAYDIUM touchscreens with positive results.

  [Regression Potential]
  Medium.
  commit e04a0442 is included by 4.16 kernel, only bionic kernel should be 
applied.
  This commit is based on the other 3  patches, mostly changes are moving codes 
to hid-quirk.c.
  Backports are during to the other backports patches, these changes are moved 
to
  hid-quirk.c too.
