quirks: Customize ALPS i2c touchpad palm detect pressure threshold

Browse source 
ALPS i2c touchpad support ABS_PRESSURE and ABS_MT_PRESSURE capabilities,
The default threshold 130 is too easy to across while finger movement.
It will cause the cursor stalled after the threshold is achieved, which
impacts user experience.
Test with some ALPS touchpads 0488:101A, 0488:101D, 0488:101E, the value
180 is good on those platforms.
