mainboard: remove "recovery" gpio, selectively add "presence" gpio.
The gpio table is only used by depthcharge, and depthcharge rarely has a need for the "recovery" gpio. On a few boards it does use the gpio as a signal for confirming physical presence, so on that boards we'll advertise the board as "presence". All these strings probably should have been #defines to help avoid typos (e.g., the "ec_in_rw" in stout seems questionable since everybody else uses "EC in RW"). Cq-Depend: chromium:1580454 BUG=b:129471321 BRANCH=None TEST=Local compile and flash (with corresponding changes to depthcharge) to 2 systems, one with a "presence" gpio and another without. Confirmed that both systems could enter dev mode.
