msm: display: reduce timeline to 1 for smart panel

For smart display, dsi command and wfd, since it has its
own buffer, the input buffer can be released once the
display commit finishes, hence the fence threshold for
creation can be smaller. This patch reduce the timeline
from 2 to 1 for samrt panels. Also, it needs to
wait4dmap/wait4ov after kicked off. Otherwise, tearing may
happen.
