drm/i915: Introduce intel_panel_compute_config()
Let's introduce a compute_config() helper for fixed mode panels.
For now all it does is the fixed_mode->adjusted_mode copy.
Note that with sDVO we have to ask the external encoder chip
to spit out our actual display timings for us, so the fixed_mode
to adjusted_mode copy done by intel_panel_compute_config() is
redundant, but we still want to use it to do other checks for us
later. We'll be fine so long as we only call it before
intel_sdvo_get_preferred_input_mode() overwrites adjusted_mode
with the timings from the encoder.
v2: Use intel_panel_compute_config() with sDVO
