disp: msm: add connector state along with crtc state to detect modeset

Selaa lähdekoodia 
During modeset, private mode changed is detected from
msm_display_mode which is present in sde_connector_state.
In the current code, sde_connector_state is found from the
drm_connector variable which will not be valid
during atomic check phase and new connector state is
required here. To handle this, drm_connector_state is passed
along with the drm_crtc_state while detecting
msm_atomic_needs_modeset condition.
