All avs drivers have now been moved to their corresponding soc specific
directories. Additionally, they don't depend on the POWER_AVS Kconfig
anymore. Therefore, let's simply drop the drivers/power/avs directory
altogether.

This moves all power supply drivers from drivers/power/
to drivers/power/supply/. The intention is a cleaner
source tree, since drivers/power/ also contains frameworks
unrelated to power supply, like adaptive voltage scaling.

This patch adds new driver for Active-semi ACT8945A ActivePath
charger (part of ACT8945A MFD driver) providing power supply class
information to userspace.
The driver can be configured through DT (such as, total timer,
precondition timer and input over-voltage threshold).

This patch adds support for the tps65217 charger driver. This driver is
responsible for controlling the charger aspect of the tps65217 mfd.
Currently, this mainly consists of turning on and off the charger, but
some other features of the charger can be supported through this driver.

Both the LTC2941 and LTC2943 measure battery capacity.
The LTC2943 is compatible with the LTC2941, it adds voltage and
temperature monitoring, and uses a slightly different conversion
formula for the charge counter.
To avoid confusion with e.g. the LTC2945, the driver is called
LTC2941 instead of LTC294X.
v2: Fix units of measurement: uV, uA and centidegrees.
v3: Correctly set configuration register. Allow negative values
for the sense resistor.
v4: Run checkpatch.pl and fix all errors and warnings.
v5: Prefix "lltc," to devicetree properties.

Add new driver for Maxim 77693 switch-mode charger (part of max77693
MFD driver) providing power supply class information to userspace.
The charger has +20V tolerant input. Current input can be set from 0 to
2.58 A. The charger can deliver up to 2.1 A to the battery or 3.5 A to
the system (when supplying additional current from battery to system).
The driver is configured through DTS (battery and system related
settings) and sysfs entries (timers and top-off charging threshold).
