SM5803: Re-start charging on recoverable errors
Some charging failures, such as over voltage charging from the primary
charger or over temperature on either charger, are recoverable. When
a charging failure interrupt comes from one of these causes, re-enable
sinking on the active charger chip unless charging from this chip has
yielded too many errors in the last minute.
BRANCH=None
BUG=b:166924833
TEST=on drawlat, charge up to 100% and observe sinking will re-enable
after an overvoltage interrupt
