Jiaxun Yang 9c301133be platform/x86: ideapad-laptop: Disable touchpad_switch for ELAN0634 
commit f419e5940f upstream.

Newer ideapads (e.g.: Yoga 14s, 720S 14) come with ELAN0634 touchpad do not
use EC to switch touchpad.

Reading VPCCMD_R_TOUCHPAD will return zero thus touchpad may be blocked
unexpectedly.
Writing VPCCMD_W_TOUCHPAD may cause a spurious key press.

Add has_touchpad_switch to workaround these machines.
