drivers/gpio_keys: Add label to set input device name
Added the label field to the gpio_keys _DSD so that the kernel driver
can use a meaningful name instead of the generic _HID PRP0001.
BUG=b:184593945
BRANCH=puff
TEST=build image and verify with evtest on puff:
/dev/input/event3: mic_mute_switch
UI event_device_info receives the proper name.
