drm/i915: disable CLKOUT_DP when it's not needed

Browse source

We currently don't support HDMI clock bending nor use SSC for DP or
HDMI on Haswell, so the only case where we need CLKOUT_DP is for VGA.

v2: - Replace the IS_ULT check for LPT-LP
    - Simplify GEN0/DBUFF0 check due to change on the previous patch
    - Also check for SBI_SSCCTL_DISABLE (Ben).
