Register for extcon notification and set charging current depending on
the detected cable type. Current values are taken from vendor kernel,
where most charger types end up setting 650mA [0].
Also enable and disable the CHARGER regulator based on extcon events.

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.
This issue was detected by using the Coccinelle software.

Use managed resource function devm_power_supply_register instead of
power_supply_register to simplify the error path by allowing unregistering
to happen automatically on error and remove.
Removing max8997_battery_remove function also as it is now redundant.
Also removing out of memory printk message after kzalloc as there is
already enough information on failure.

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
Before this patch:
$ modinfo drivers/power/supply/max8997_charger.ko | grep alias
$
After this patch:
$ modinfo drivers/power/supply/max8997_charger.ko | grep alias
alias: platform:max8997-battery

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.
