chgstv2: Unify power-on and shutdown battery thresholds
Currently, power-on battery SoC and shutdown battery SoC are
independently configured by each board. This patch will unify the
setting as follows:
CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON = 2 (don't boot if soc < 2%)
CONFIG_BATT_HOST_SHUTDOWN_PERCENTAGE = 2 (shutdown if soc <= 2%)
BATTERY_LEVEL_SHUTDOWN = 3 (shutdown if soc < 3%)
CONFIG_BATTERY_EXPORT_DISPLAY_SOC = Y (removed)
CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON_WITH_AC = 1
This allows us to show the low battery alert whenever we can because
EC doesn't inhibit power-on even if it knows the host would
immediately shut down.
With CONFIG_BATTERY_EXPORT_DISPLAY_SOC, boards will start using the
CONFIG_BATT_HOST_SHUTDOWN_PERCENTAGE = 2% as the low battery
threshold (and the SoC will be agreed between the EC and Powerd).
Boards with CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON = 1 will keep the
same threshold. This is for avoiding degrading the UX by increasing
the power-on threshold (even though a question that 1% may not be
enough for soft sync to finish consistently remains to be answered).
Boards with CONFIG_CHARGER_MIN_BAT_PCT_FOR_POWER_ON > 2 will have a
lower threshold but we think 2% is enough to finish the software sync.
A lower threshold also improves the UX by showing the low battery
alert in the situation where otherwise the system would leave the user
uninformed by not responding to a power button press.
