ACPI: toshiba_acpi: Add support for the generic backlight device
Add support for the generic backlight interface below /sys/class/backlight.
Keep the procfs brightness handling for backward compatibility.
To achive this, add two generic functions get_lcd and set_lcd
to be used both by the procfs related and the sysfs related methods.
