POWER_SUPPLY_PROP_CHARGING_ENABLED has been used to indicate enabling
the charge path in some drivers and enabling the input path in others.
This leads to confusion of what charging enabled really means.
POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED was introduced to indicate
enabling the charge path, and in this case
POWER_SUPPLY_PROP_CHARGING_ENABLED is used to indicate enabling the
input path. Since these are similarly named it leads to even more
confusion.
In an attempt to fix this confusion we introduce a new power supply
property POWER_SUPPLY_PROP_INPUT_SUSPEND which indicates suspending the
input path of the power supply. POWER_SUPPLY_PROP_CHARGING_ENABLED takes
its original definition of enabling the charge path. Then
POWER_SUPPLY_PROP_BATTERY_CHARGING_ENABLED will be retired from use.
