The trackpad bits in the DTS needed some love. This adds some basic infrastructure support in the main gru dts file and then adds the specific trackpad used on kevin-r0 and kevin-r1. For now just duplicate between kevin-r0 and kevin-r1 and we'll decide if we want to share later (perhaps we want an "atmel" snippet?). Note that gpio-keymap here makes the driver appear as a trackpad rather than a touchscreen (driver assumes that anything with buttons is a trackpad). Input entry corresponding to the button on the trackpad was found by experimentation as suggested in the device tree bindings. BUG=chrome-os-partner:52637 TEST=With series, trackpad works in browser; button works.
