Hans de Goede 2220af8ca6 power: supply: core: Refactor power_supply_set_input_current_limit_from_supplier() 
Some (USB) charger ICs have variants with USB D+ and D- pins to do their
own builtin charger-type detection, like e.g. the bq24190 and bq25890 and
also variants which lack this functionality, e.g. the bq24192 and bq25892.

In case the charger-type; and thus the input-current-limit detection is
done outside the charger IC then we need some way to communicate this to
the charger IC. In the past extcon was used for this, but if the external
detection does e.g. full USB PD negotiation then the extcon cable-types do
not convey enough information.

For these setups it was decided to model the external charging "brick"
and the parameters negotiated with it as a power_supply class-device
itself; and power_supply_set_input_current_limit_from_supplier() was
introduced to allow drivers to get the input-current-limit this way.

But in some cases psy drivers may want to know other properties, e.g. the
bq25892 can do "quick-charge" negotiation by pulsing its current draw,
but this should only be done if the usb_type psy-property of its supplier
is set to DCP (and device-properties indicate the board allows higher
voltages).

Instead of adding extra helper functions for each property which
a psy-driver wants to query from its supplier, refactor
power_supply_set_input_current_limit_from_supplier() into a
more generic power_supply_get_property_from_supplier() function.
