Fizz: Detect BJ as a power source
Proto2 board has the line ADP_IN, which is raised to 2.5 V when a BJ
adapter is plugged. This patch makes EC running on proto2 and above
use this line to detect the power source at boot (as opposed to proto1
guessing a BJ adapter is plugged if PPVAR_BOOSTIN_SENSE is 19v).
BUG=b:37573548
BRANCH=none
TEST=Boot proto3 Fizz on BJ and Type-C.
