[PATCH 5/11] Add backlight support to the sony_acpi v2

[malattia@linux.it]

From: Alessandro Guido <alessandro.guido@gmail.com>

Enable the sony_acpi driver to use the backlight subsysyem for adjusting
the monitor brightness.  Old way of changing the brightness will be still
available for compatibility with existing tools.
