The X-Powers AXP20X and AXP22X PMICs expose the status of AC power
supply.
Moreover, the AXP20X can also expose the current current and voltage
values of the AC power supply.
This adds the driver which exposes the status of the AC power supply of
the AXP20X and AXP22X PMICs.

The added regulator dependency in the smbb driver causes build errors
when regulators are disabled, e.g. in randconfig build testing:
drivers/power/supply/qcom_smbb.o: In function `smbb_chg_otg_is_enabled':
qcom_smbb.c:(.text.smbb_chg_otg_is_enabled+0x18): undefined reference to `rdev_get_drvdata'
drivers/power/supply/qcom_smbb.o: In function `smbb_charger_probe':
qcom_smbb.c:(.text.smbb_charger_probe+0x410): undefined reference to `devm_regulator_register'
This adds a Kconfig dependency to avoid the link error.

The MAX14656 USB charger detector, also known as "AL32" is used to detect
the presence and capabilities of attached USB chargers. The device is
attached via I2C plus one interrupt line to signalize events.
The device can be found in LG smartphones like LS665 and LS770, compatible
devices are present in 4th/5th generation Amazon Kindle readers referenced
in source code packages as "Maxim AL32".
The initial version of this driver has been extracted from LG source code
package LGLS665_Android_Lollipop_LS665ZV3, enriched with information from
the Kindle_src_4.1.3 source code package and adapted to the current power
class sysfs interface. Non-Standard Apple chargers which the device may
detect are mapped to the USB Battery Charging Specification Revision 1.2
class USB_DCP.

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.
