commit 1311c3521e4d73aaaeffc60f528431b6f2d3f5cf

    Set DFP Low delay tap for P4M900 family from via_lvds_mode_set
    
    Rather than setting DFP (Digital Flat Panel) delay tap value
    from viaIGA2SetDisplayRegister function inside via_display.c,
    it will now be set from via_lvds_mode_set callback function
    inside via_lvds.c. For now, this is only applicable for
    P4M900 / VN896 / CN896 chipsets.

    Added viaDFPLowSetDelayTap
    
    viaDFPLowSetDelayTap function sets the delay tap value for
    DFP (Digital Flat Panel) Low interface. This function is located
    inside via_lvds.c.
