disp: msm: update seamless check for connector

Selaa lähdekoodia 
During CWB case where writeback connector is disabled
and connectors_changed is set, add support to allow
disabling of corresponding encoder for this connector.
Modify the seamless check for connector to handle
the same. With this cwb + dfps concurrency can
be handled.
