HID: google: Add support for vivaldi to hid-hammer
Add support to the hammer driver to parse vivaldi keyboard layouts and
expose them to userspace. This allows hammer devices to use vivaldi
function row keys while also supporting the other features this driver
supports, like the CBAS (chrome base attached switch) and a keyboard
backlight.
