buttons: Make buttons[] common.
Nearly every board had a buttons array defined in which its contents had
the standard volume buttons. This commit creates a single common
buttons array that can contain the standard volume buttons and recovery
buttons. If a board has volume up and down buttons, they can simply
define CONFIG_VOLUME_BUTTONS and it will populate the buttons array with
the standard definition. The buttons are active low and have a 30 ms
debounce period. Similiarly, if a board has a dedicated recovery
button, defining CONFIG_DEDICATED_RECOVERY_BUTTON will also populate the
buttons array with a recovery button.
BUG=chromium:783371
BRANCH=None
TEST=make -j buildall.
TEST=Flash a device with CONFIG_VOLUME_BUTTONS, verify pressing volume
buttons still work.
