drm/msm/sde: fix flush configuration for physical encoder
The sde encoder merges the flush for both controller but
does not configure the split_flush_enable on mdp_top.
This causes stage-1 fault or vsync_failure because right
side lm/sspp are not getting updated on each update. This
patch enables the split_flush only for pingpong split case
and also checks the vsync status on correct register.
