mb/google/puff/var/dooly: Add gpio_keys for mic mute switch
UI monitors this input event and sends global mic mute command to CRAS
when the physical switch is toggled.
BUG=b:184593945
BRANCH=puff
TEST=build image and verify with evtest on DUT.
Apply crrev.com/c/2870806 with chrome cmdline flag and verify global
mute is triggered.
Verify sequences of switch toggle and suspend/resume.
