Zhao, Yakui Sept. 11, 2009, 3:49 a.m. UTC 
From: Zhao Yakui <yakui.zhao@intel.com>

When the sdvo device is detected as SDVO-TV, we will check whether the
sepecific picture enhancement is supported. If it is supported, we will
add the corresponnding property for SDVO-TV. We will add the following
property for the SDVO-TV enhancements if they are supported:
   Contrast/Brightness/Saturation/Hue:
   left/right/top/bottom margin: This is implemented by using the horizontal/
vertical overscan enhancements. When the overscan enhancements are supported,
the above properties will be added. This is to be compatible with what we have
done in integrated-TV.
   horizontal pos/vertical pos:
