Input: ili210x - add missing negation for touch indication on ili210x
commit ac05a8a927e5a1027592d8f98510a511dadeed14 upstream.
This adds the negation needed for proper finger detection on Ilitek
ili2107/ili210x. This fixes polling issues (on Amazon Kindle Fire)
caused by returning false for the cooresponding finger on the touchscreen.
