disp: msm: sde: avoid solver mode if autorefresh is enabled

In dual display with continuous splash, when autorefresh gets
disabled in primary on first commit, solver mode gets enabled
and mdp_clock is gated whenever primary enters idle. The
secondary data path will get gated during that time and not advance
anymore. Asynchronous gating of the mdp_clock during operation
can also hang the secondary path. This change avoids entering
the solver mode which fixes the timeout in the autorefresh
disable sequence in the secondary.
