Ryu: Add a console command to control the buttons VolUp and VolDown

Browse Source 
(cherry-pick back to ToT)

FAFT needs these buttons (VolUp and VolDown) be controllable
such that it can automate the firmware mode switching flows.
It is done by EC overwriting the GPIO values such that AP can
see the results.

BRANCH=ToT,smaug
BUG=None
TEST=AP boots into the firmware menu screen. Run the following commands
in EC console:
> btnpress voldown 1
> btnpress voldown 0  # See the next option selected, like a real button pressed
> btnpress volup 1
> btnpress volup 0  # Boot in the selected option, like a real button pressed
> btnpress volup
Button volup pressed = 0
