Disable core keyboard device as well when entering touchview.

Repeated keypress events seem to be coming from the core keyboard device for the internal keyboard. Amazingly, they seem to come from the correct device (for my external keyboard at least) so this patch may be all we need.

BUG=402868
TEST=Flip open device past 180 to enter touchview. Hold a key on keyboard. Key is not typed. External keyboard still works while in touchview.
