This needs re-wording.

Currently, struct drm_dsc_config is retrieved from DSI driver in 
dpu_encoder_setup_display() and this model works for non-pluggable 
displays. However this does not scale for pluggable displays because the 
struct drm_dsc_config is no longer valid after a disconnect and needs to 
be retrieved from the sink again.

Move retrieval of struct drm_dsc_config from dpu_encoder_setup_display() 
to dpu_encoder_virt_atomic_enable() to make the code path common between 
pluggable and non-pluggable displays.

And also delete struct drm_dsc_config from struct msm_display_info as it 
will now be unused.
