[PATCH 4/7] power_supply: add throttle state

[Jenny TC]

The charger and battery temperature contribute to the
platform thermal. The only way to control the temperature
is to control the charging. The charging can be controlled in different
way. This could be disabling charger, disabling charging, adjusting CC,
or by adjusting the INLMT. This patch adds a structure to define the
charger throttle actions. Also this patch adds a throttle_states
field to the struct power_supply which can be used by the charger
driver to define it's throttle actions for different states
