[Intel-gfx] [Patch 2/2] DRM/I915: Add the brightness property for SDVO-LVDS

[yakui.zhao at intel.com]

From: Zhao Yakui <yakui.zhao at intel.com>

When the sdvo device is detected as SDVO-LVDS, we will check whether the
brightness is supported by issue SDVO enhancement command.
If it is supported, we will add the brightness property and then brightness
can be adjusted.
