HID: intel-thc-hid: Intel-quicki2c: Enhance driver re-install flow

After driver module is removed and during re-install stage, if there
is continueous user touching on the screen, it is a risk impacting
THC hardware initialization which causes driver installation failure.

This patch enhances this flow by quiescing the external touch
interrupt after driver is removed which keeps THC hardware
ignore external interrupt during this remove and re-install stage.
