Change the ownership of power_supply structure from each driver
implementing the class to the power supply core.
The patch changes power_supply_register() function thus all drivers
implementing power supply class are adjusted.
Each driver provides the implementation of power supply. However it
should not be the owner of power supply class instance because it is
exposed by core to other subsystems with power_supply_get_by_name().
These other subsystems have no knowledge when the driver will unregister
the power supply. This leads to several issues when driver is unbound -
mostly because user of power supply accesses freed memory.
Instead let the core own the instance of struct 'power_supply'. Other
users of this power supply will still access valid memory because it
will be freed when device reference count reaches 0. Currently this
means "it will leak" but power_supply_put() call in next patches will
solve it.
This solves invalid memory references in following race condition
scenario:
Thread 1: charger manager
Thread 2: power supply driver, used by charger manager
THREAD 1 (charger manager) THREAD 2 (power supply driver)
========================== ==============================
psy = power_supply_get_by_name()
Driver unbind, .remove
power_supply_unregister()
Device fully removed
psy->get_property()
The 'get_property' call is executed in invalid context because the driver was
unbound and struct 'power_supply' memory was freed.
This could be observed easily with charger manager driver (here compiled
with max17040 fuel gauge):

Add new structure 'power_supply_config' for holding run-time
initialization data like of_node, supplies and private driver data.
The power_supply_register() function is changed so all power supply
drivers need updating.
When registering the power supply this new 'power_supply_config' should be
used instead of directly initializing 'struct power_supply'. This allows
changing the ownership of power_supply structure from driver to the
power supply core in next patches.
When a driver does not use of_node or supplies then it should use NULL
as config. If driver uses of_node or supplies then it should allocate
config on stack and initialize it with proper values.

Now that we always pass platform specific battery management data
through platform_data instead of obtaining it via different means
depending the way be boot the system (DT or ATAGs); we need to
re-jiggle the way we acquire it in the driver start-up functions.
Now it is wrong for it to be missing, but we still allow Device
Tree code to fiddle with it once we've confirmed it's there.
Signed-off-by: Lee Jones <lee.jones@linaro.org>
Currently the AB8500 battery management subsystem receives platform
specific information via two different means depending on how the
platform is booted. If DT is not enabled, a reference to a *_bm_data
data structure containing each platform specific attribute is passed
though platform_data. However, if DT is enabled, then platform_data
is empty and the reference is gained though a DT specific probe
function. There are two issues here 1) the same reference is
being collected each time and 2) the DT way doesn't allow any
provisions to select different platform specific attributes, which
kind of defeats the object.

The platform specific battery management configuration data structure
is currently called 'bat' short for 'battery'; however, it contains
information for all components of the battery management group, rather
than information pertaining to the battery itself - there are other
structures for that. So, in keeping with its structure namesake
'abx500_bm_data', we rename it to 'bm' here. Using similar logic,
we're also renaming 'bmdevs_of_probe' to the more device specific
'ab8500_bm_of_probe'.

- Marvell 88pm860x charger and battery drivers;
- Texas Instruments LP8788 charger driver;
2. Two new power supply properties: whether a battery is authentic, and
chargers' maximal currents and voltages;
3. A lot of TI LP8727 Charger cleanups;
4. New features for Charger Manager, mainly now we can disable specific
regulators;
5. Random fixes and cleanups for other drivers.
