google/cyan: Switch Touchpad and Touchscreen interrupts to be level-triggered

Browse Source 
Adapted from chromium commit 126d352
[Strago: switch Touchpad and Touchscreen interrupts to be level-triggered]

The Elan and other touch controllers found in this device work much
more reliably if used with level-triggered interrupts rather than
edge-triggered.

TEST=Boot several cyan boards, verify that touchpad and touchscreen
work.
