Common battery cut-off host command / console command infrastructure already exists behind CONFIG_BATTERY_CUT_OFF, so add the config rather duplicating the code at the board level. BUG=chromium:488157 TEST=Manual on Squawks. Verify that both "cutoff" on the ec console and "ectool batterycutoff" succeed to cut-off the battery.
