drm/msm/sde: introduce sde_mdp_vsync_sel feature flag in top blk

This change introduces a new flag, SDE_MDP_VSYNC_SEL, for SDE
TOP block. This feature flag is enabled during the catalog
initialization phase based on mdss hw version. sde top module
uses this feature flag to assign correct op to configure TE
vsync configuration for command mode panels.

This change, by default, disables the new feature flag for
all sde versions with major revision greater than 4 as
vsync_sel is in interface block te from sde 5.0.0 onwards.

This change also disables SDE_PINGPONG_TE feature for sde 5.0.0
as it supports interface te block.
