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.
