zoombini: Add BC1.2 support.

Browse Source 
This commit enables the use of the TI BQ24932 charger detector.
Additionally, the charge ramping config option is turned on as the
ISL9238 supports HW based charge ramping.

BUG=none
BRANCH=none
TEST=`make -j buildall`
TEST=Flash modified version on npcx7_evb and verify no panics or asserts
are hit.
