disp: msm: add support for seamless dsc switch

Browse Source 
This change adds logic to determine dsc switch based on
the connector property "CONNECTOR_PROP_DSC_MODE" and
performs seamless DSC switch if there is any change in
DSC configuration. The connector property is populated
in msm_sub_mode based on which suitable mode is selected.
