Add support for keyboard matrix version 3.0. To enable it, define

I might be wrong but it looks to me if one enables support for v3 keymap
then the kernel will not work for devices using other/older versions of
keymap. It might be acceptable for Chrome OS kernels but will nto work
for upstream.

I think you need to create arch/arm/boot/dts/cros-ec-keyboard-v3.dtsi
that would define "keyboard_controller" node with proper keymap and
include this new dtsi into std files for devices/boards that need it.

Thanks.
