samus: turn on PP5000 when AC is attached in G3
Turn on PP5000 when AC is plugged in in G3 so that the PD
MCU can accurately measure the CC voltage.
BUG=chrome-os-partner:33909
BRANCH=samus
TEST=test with various type-C chargers. verify that in G3 the
pp5000 rail is on when AC is plugged in, but off when AC is
unplugged
used reported battery current to estimate that turning on
PP5000 rail in G3 consumes an extra 30mW of power, but that
shouldn't matter much when AC is connected.
