disp: msm: sde: fix autorefresh enable/disable sequence

Browse Source 
SDE RSCC solver state and autorefresh enable concurrency
is not supported. This change moves the rscc solver state
to disable to avoid concurrency. It also resets the autorefresh
software structure state when encoder is disabled. This allows
autorefresh reconfiguration with next encoder enable.
