Jani Nikula a94a6d76c9 drm/i915/mst: abstract intel_dp_mst_source_support()
Add a function for checking source MST support. Drop intel_dp->can_mst
and use intel_dp->mst_mgr.cbs to indicate the same. It's the single
point of truth without additional state variables. In code, "source
support" is also self-documenting as opposed to the vague "can mst".
