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.

The driver mismatched 'num_supplicants' with 'num_supplies' of
power_supply structure.
It provided list of supplicants (power_supply.supplied_to) but did
not set the number of supplicants. Instead it set the num_supplies which
is used when iterating over number of supplies (power_supply.supplied_from).
As a result the list of supplicants was ignored by core because its size
was 0.

For __i386__ builds we have:
arch/x86/include/uapi/asm/ptrace-abi.h:#define SS 16
And in the driver:
BQ24190_SYSFS_FIELD_RO(vbus_stat, SS, VBUS_STAT)
That breaks the build like this:
drivers/power/bq24190_charger.c:375:138: error: ‘BQ24190_REG_16’
undeclared here (not in a function)
drivers/power/bq24190_charger.c:375:162: error:
‘BQ24190_REG_16_THERM_STAT_MASK’ undeclared here (not in a function)
drivers/power/bq24190_charger.c:375:203: error:
‘BQ24190_REG_16_THERM_STAT_SHIFT’ undeclared here (not
in a function)
With this commit we workaround the problem by undefining 'SS'.

Add driver support for the Texas Instruments BQ24190 battery charger.
Some of the information provided by the device is about the charger and
other information is about the battery so create two power_supply objects
(one for each) and provide the appropriate information for each one.
The device has many fields that go beyond what is reasonable to report or
modify using the existing 'POWER_SUPPLY_PROP_*' properties so the driver
exports the register fields via sysfs. They are prefixed by 'f_' (for
'field') to make it easier to distinguish between a register field and a
"normal" sysfs file exported by the power_supply infrastructure.
