disp: msm: sde: add vsync count in virtual encoder

Browse Source 
Introduce vsync count variable in virtual encoder structure
to keep the vsync count variable value in sync while performing
the poms. Consequently, this prevents the blocking of
drm_vblank_put and the invocation of
drm_crtc_funcs.disable_vblank.
