    drm/i915: get rid of dev_priv->info->has_pch_split · 45e6e3a1

    Previously we had has_pch_split to tell us whether we had a PCH or not
    and we also had dev_priv->pch_type to tell us which kind of PCH it
    was, but it could only be used if we were 100% sure we did have a PCH.
    Now that PCH_NONE was added to dev_priv->pch_type we don't need
    has_pch_split anymore: we can just check for pch_type != PCH_NONE.
    
    The HAS_PCH_{IBX,CPT,LPT} macros use dev_priv->pch_type, so they can
    only be called after intel_detect_pch. The HAS_PCH_SPLIT macro looks
    at dev_priv->info->has_pch_split, which is available earlier.
    
    Since the goal is to implement HAS_PCH_SPLIT using dev_priv->pch_type
    instead of dev_priv->info->has_pch_split, we need to make sure that
    intel_detect_pch is called before any calls to HAS_PCH_SPLIT are made.
    So we moved the intel_detect_pch call to an earlier stage.
