nyan: Ignore the recovery GPIO.

CrOS devices with Chromeos EC need only use hostevent to communicate
recovery assertion to the BIOS.  This CL removes wired GPIO from
determining recovery as it appears under certain conditions (cold
reset) the internal PU on the AP isn't strong enough and therefore the
value is sometimes seen as asserted.

BRANCH=none
BUG=chrome-os-partner:29333
TEST=compiles & BIOS no longer responds to rec_mode GPIO during boot.
