ACPI: ibm_acpi: Add support for the generic backlight device

Add support for the generic backlight interface below /sys/class/backlight.
The patch keeps the procfs brightness handling for backward compatibility.

Add two generic functions brightness_get and brightness_set
to be used both by the procfs related and the sysfs related methods.

[apw@shadowen.org: backlight users need to select BACKLIGHT_CLASS_DEVICE]
