Allow drivers to store private data inside power_supply structure for
later usage in power supply operations.
Usage of driver private data is necessary to access driver's state
container object from power supply calls (like get_property()) if struct
'power_supply' is a stored there as a pointer, for example:
struct some_driver_info {
struct i2c_client *client;
struct power_supply *power_supply;
...
}
In such case one cannot use container_of() and must store pointer to
state container as private data.
