[Impact]
The current kernel didn't support multitouch for LG I2C touchscreen.

[Fix]
Add LG I2C id to hid-multitouch to support it.

[Test]
Verified on hardware with a positive result.

[Regression Potential]
Low.
Add new I2C id with positive verification.

This patch is backported from maintainer's tree.
