battery: Add the battery hooking API This is a patch that implements a generic hooking API for the generic ACPI battery driver. With this new generic API, drivers can expose platform specific behaviour via sysfs attributes in /sys/class/power_supply/BATn/ in a generic way. A perfect example of the need for this API are Lenovo ThinkPads. Lenovo ThinkPads have a ACPI extension that allows the setting of start and stop charge thresholds in the EC and battery firmware via ACPI. The thinkpad_acpi module can use this API to expose sysfs attributes that it controls inside the ACPI battery driver sysfs tree, under /sys/class/power_supply/BATN/. The file drivers/acpi/battery.h has been moved to include/acpi/battery.h and the includes inside ac.c, sbs.c, and battery.c have been adjusted to reflect that. When drivers hooks into the API, the API calls add_battery() for each battery in the system that passes it a acpi_battery struct. Then, the drivers can use device_create_file() to create new sysfs attributes with that struct and identify the batteries for per-battery attributes.

ACPI: battery: add devm_battery_hook_register() Add a utility function for device-managed registration of battery hooks. The function makes it easier to manage the lifecycle of a hook.

ACPI: battery: include linux/power_supply.h acpi/battery.h uses 'struct power_supply *', but fails to include/create any declaration of the type. Include linux/ power_supply.h to fix that.

ACPI: battery: Pass battery hook pointer to hook callbacks Right now, is impossible for battery hook callbacks to access instance-specific data, forcing most drivers to provide some sort of global state. This however is difficult for drivers which can be instantiated multiple times and/or are hotplug-capable. Pass a pointer to the battery hook to those callbacks for usage with container_of().
