    Set LVDS2 delay tap for CX700 family from via_lvds_mode_set
    
    Rather than setting LVDS2 (LVDS Channel 2) integrated LVDS
    transmitter delay tap value from viaSetLVDSOutput function, it will
    now be set from via_lvds_mode_set callback function. This change is
    only applicable to CX700 / VX700 chipsets.

    Added viaLVDS2SetDelayTap
    
    viaLVDS2SetDelayTap function sets the delay tap value for LVDS2
    (LVDS Channel 2) integrated LVDS transmitter. This function is
    located inside via_lvds.c.
