coral: Remove LIMIT_POWER config options
coral: 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.
