kohaku: enable CONFIG_BATTERY_CHECK_CHARGE_TEMP_LIMITS
Enable the CONFIG_BATTERY_CHECK_CHARGE_TEMP_LIMITS option so that
when charging stops due to battery overtemperature, the battery LED
will be green regardless of the state of charge of the battery.
BUG=b:140596424
BRANCH=None
TEST=`make -j BOARD=kohaku && ./util/flash_ec --board=kohaku`
Ensure battery is not fully charged

> batttempfake 3300
This overrides the normal temperature read and forces the value to
330.0 K, which is 56.9 C. The Kohaku battery has a maximum charge
temperature of 55 C, and a maximum discharge temperature of 60 C,
so this temperature is hot enough to stop charging, but not so hot
that the system will shut down.
