Subject: [PATCH v5 3/3] power_supply: Add missing documentation for CHARGE_CONTROL_* properties

The existing POWER_SUPPLY_PROP_CHARGE_CONTROL_LIMIT and
POWER_SUPPLY_PROP_CHARGE_CONTROL_LIMIT_MAX properties
don't have documentation. I add that documentation here.

v5 changes:
- Split this commit out from the previous two commits.
