pyro/snappy: Add CONFIG option to maintain VBAT voltage
Follow reef setting.
On the bd9995*, back boosting may occur when actual battery voltage
drops below VBAT register setting. Maintain the VBAT register at the
battery-requested charge voltage even when not charging to ensure the
bd9995* doesn't become a back boosted animal.
BUG=none
BRANCH=reef
TEST=make buildall
