Subject: [PATCH v3 3/5] Introduce CONFIG_GOOGLE_FIRMWARE

In order to keep Google's firmware drivers organized amongst themselves,
create a new directory for them to live in.  As well, all Google
firmware drivers are gated on CONFIG_GOOGLE_FIRMWARE=y, which defaults
to 'n' in the kernel build.

Signed-off-by: Mike Waychison <mikew@...gle.com>
