touchpad: Disable edge palm detection Apple touchpads

Browse source 
This hurts more than it helps, and users complain of dead trackpad
edges. Apple touchpads have fairly sophisticated internal palm rejection
algorithms going back many years, so let's just disable this one on
everything Apple.

Related to: #433 (need to figure out what other hardware may need this)
