[Impact]
Goodix touchpads in general don't work well. Sometimes not working at
all.

[Fix]
Remove runtime pm from HID over I2C driver. The power saving is little
to none and causes many problems.

[Test]
After applying the fix, which removes runtime pm, the Goodix touchpad
works like a charm.

[Regression Potential]
Low. This actually mimics behavior on Windows.
