Casta: Adjust charger configs for low battery booting 

When a locked system boots up with a very low or non-communicating
battery, the DUT should refrain from booting S0 in order to avoid hard
reset brown outs after the system jumps to RW and begins attempting PD
negotiation.

BUG=b:131126731
BRANCH=octopus
TEST=loaded onto locked casta with low battery, verified that the
system didn't boot to S0 until the battery had passed the min
battery percent configuration
