BD99955: Use only one USB charger task for both the ports
There is only one charger IC and one interrupt PIN for both the ports
and also from the ISR it's not possible to decode from which port the
interrupt is triggered hence a deferred function is used to trigger
the wake event for the ports. As there is no additional benefit of
having an extra task, added code to use only one USB charger task for
both the ports.
BUG=chrome-os-partner:54272
BRANCH=none
TEST=Manually tested on Amenia. BC1.2 detection is success
and the battery can charge on both the ports (VBUS/VCC).
