Fleex: Set minimum battery level for Try.SRC and resets
Some battery and fuel gague combinations for fleex are unable to
withstand the loss of a charger's Vbus signal when they are reporting 1%
charge. This change increases the Try.SRC battery required, and also
prevents the PD state machine from starting reset timers until the
battery is at 2%.
BUG=b:128935567
BRANCH=octopus
TEST=verified hard resets don't occur on grabbiter when system is locked
and coming back from battery cutoff with low battery, verified soft
followed by hard reset later occurs when battery passes config level
