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.

Write protection (get_write_protect_state) was hard-coded to 0 and
should be fixed to read from correct GPIO (PERIPHERAL_EN0 from
schematics).

For Kukui CR50_IRQ pin, we're going to replace external pull-up with
internal pull-up. This change won't break older boards, so we can just
always do that when setting up GPIOs.

Set up EC_IN_RW GPIO to boot depthcharge. Without this patch,
depthcharge will fail to tell if the EC firmware is RW.
