poppy: Remove LIMIT_POWER config options
poppy: Remove LIMIT_POWER config options

These config options change the behavior of charge_prevent_power_on
and ignore the minimum battery percentage for booting. Since we don't
have any AP code to actually handle this state, we don't want it to
always boot the AP or it might brown out with a battery that is
critically low.

BUG=b:64460667
BRANCH=None
TEST=manual testing with low battery to ensure it does not attempt to
boot the AP.
