    drm/panel: sitronix-st7789v: fix timing for jt240mhqs_hwt_ek_e3 panel
    
    [ Upstream commit 0e5895ff7fab0fc05ec17daf9a568368828fa6ea ]
    
    Flickering was observed when using partial mode. Moving the vsync to the
    same position as used by the default sitronix-st7789v timing resolves this
    issue.
