stm32: Fix polarity of charger interrupt
The charger interrupt is active-low. Snow and Spring properly
triggered on falling (asserting) edge, but Pit (and Daisy/Puppy)
didn't. Fix those boards, and rename the signal to end in _L so we
don't make that mistake again.
BUG=chrome-os-partner:22827
BRANCH=pit
TEST=unplug/replug AC adapter on pit; see debug output as follows:
[batt] state charging -> idle0
Charger IRQ received.
[batt] state idle0 -> charging
Charger IRQ received.
