drm/i915: Always use SDVO_B detect bit for SDVO output detection.

After the following commit is shipped, the SDVO C detection will depend on
the SDVO_C/DP detion bit.

    drm/i915: Read the right SDVO register when detecting SVDO/HDMI.

According to the spec we should continue to detect the SDVO_B/C based on
the SDVO_B detection bit.  The new detection bit on G4X platform is for
the HDMI_C detection rather than SDVO_C detection.
