qpnp-smb2: support setting FCC and float voltage in battery power supply
Fast charge current (FCC) and float voltage are parameters that
are battery specific and needs to be set based on the profile
detected by Fuel Gauge driver. Expose the following properties
from battery power supply so that FG can set them.
- POWER_SUPPLY_PROP_VOLTAGE_MAX
- POWER_SUPPLY_PROP_CONSTANT_CHARGE_CURRENT_MAX
