drm/i915: add encoder get_config function v5
We can use this for fetching encoder specific pipe_config state, like
mode flags, adjusted clock, etc.
Just used for mode flags atm, so we can check the pipe config state at
mode set time.
v2: get_config when checking hw state too
v3: fix DVO and LVDS mode flags (Ville)
get SDVO DTD for flag fetch (Ville)
v4: use input timings (Ville)
correct command used (Ville)
remove gen4 check (Ville)
v5: get DDI flag config too
