nouveau: Add in-kernel backlight control support
Several nvidia-based systems don't support backlight control via the standard ACPI control mechanisms. Instead, it's necessary for the driver to modify the backlight control registers directly. This patch adds support for determining whether the registers appear to be in use, and if so registers a kernel backlight device to control them. The backlight can then be controlled via existing userspace tools. Signed-off-by: Matthew Garrett <mjg@redhat.com> Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
