drm/msm/sde: use current encoders to determine crtc interface

Browse source 
Instead of using the cached interface type, which is updated
during fence preparation time, determine interface type by
enumerating over all matching encoders and query the interface
directly. This avoids pontential stale interface types due to
changing connector state.
