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.

Veyron was an rk3288 board. Having it in the compatible doesn't make a
ton of sense. We'll stick 'gru' in the kevin name, though, since that
sorta makes sense. Not that we ever really fall back to this stuff.
BUG=None
TEST=Build and boot

Turns out that we got mixed up. Old stuff should just be rev 0. New
stuff should be rev 1+. Fix all that.
BUG=None
TEST=Boot rev 0.

Some pinctrl stuff has moved around and will be identical between gru
and kevin going forward, so kevin r1-specific things will be stored
in the kevin-r1 dts file.
BUG=none
TEST=kernel still boots on kevin-r1
