drm/i915: Unduplicate VLV signal level code
The logic for setting signal levels is used for both HDMI and DP with
small variations. But it is similar enough to put behind a function
called from the encoders.
v2: Remove unrelated MST changes due to rebase fumble. (Jim Bride)
Fix typo in the commit message. (Jim Bride)
v3: Really fix the typo. (Jim)
