Currently in bq27541 driver, the average power register address is
incorrectly set to 0x76, which would result in an error:
bq27xxx-battery 2-0055: error reading average power register 10: -11
According to the bq27541 datasheet, fix this problem by setting
the average power register address to 0x24.

Currently the reset/power off handlers (POWER_RESET) and Adaptive Voltage
Scaling class (POWER_AVS) are not built when POWER_SUPPLY is disabled.
The POWER_RESET is also not visible in drivers main section of config.
However they do not really depend on power supply so they can be built
always. The objects for power supply drivers already depend on
particular Kconfig symbols so there is no need for any changes in
drivers/power/Makefile.
This allows selecting POWER_RESET from main drivers config section and
fixes following build warning (encountered on ARM exynos defconfig when
POWER_SUPPLY is disabled manually):
warning: (ARCH_HISI && ARCH_INTEGRATOR && ARCH_EXYNOS && ARCH_VEXPRESS && REALVIEW_DT) selects POWER_RESET which has unmet direct dependencies (POWER_SUPPLY)

This patch adds basic support for bq24250 and bq24251 which are very
similar to the bq24257 the driver was originally written for. Basic
support means the ability to select a device through Kconfig, DT and
ACPI, an instance variable allowing to check which chip is active, and
the reporting back of the selected device through the model_name power
supply sysfs property.
This patch by itself is not sufficient to actually use those two added
devices in a real-world setting due to some feature differences which
are addressed by other patches in this series.

The maximum amount of input current the charger should draw is dependent
on the power supply and should only be (re-)configured when the power
supply gets connected and disconnected. However the driver was also
lowering the bq24257's input current limit setting to 500mA when the
battery was removed and restored the previous setting according to the
power supply capabilities when the battery was reconnected although
these events are not impacting the amount of power that can be drawn
from the supply. Furthermore, a re-configuration of the input current
limit to 500mA when the battery gets disconnected is actually dangerous
if the limit was set higher previously and the system draws more than
500mA in which case the system voltage would be reduced in order to
maintain 500mA which could result in the system getting too low of a
supply to maintain operation. Last but not least the mechanism itself
used for battery re-connection detection did not work in corner cases
such as when the device's input current loop becomes active and the
bq24257 device clears its battery fault error resulting in incorrectly
reporting that the battery got reconnected.
This patches removes the impact the battery removal/insertion has on the
input current limit configured for the bq24257 and simplifies the
associated handler routine.

At the time the driver was written GpioInt resources in ACPI were not
passed to the driver in client->irq, as opposed to DT enumeration. To
accommodate this use case, a "stat-gpios" property was introduced to
allow configuring the IRQ.
However this issue with ACPI was fixed in commit "845c877 i2c / ACPI:
Assign IRQ for devices that have GpioInt automatically" and makes this
workaround no longer necessary, hence we can remove the support for the
"stat-gpios" property and the associated code from the bq24257 driver.

Use managed resource function devm_power_supply_register instead
of power_supply_register to simplify the error path by allowing
unregister to happen automatically on error. To be compatible with
the change, replace various gotos by direct returns and remove
unneeded label err.
Also, remove max8998_battery_remove as it is now redundant.

This platform driver has a OF device ID table but the OF module
alias information is not created so module autoloading won't work.
