ViaGammaDisable function improvement patch

Made improvements to ViaGammaDisable function inside via_display.c.
 The improved code will now make sure that UniChrome graphics (CLE266, KM400,
etc.) will execute a certain code path, and UniChrome Pro and Chrome 9 graphics
will execute another code path.
It is unclear if the previous revision of the code had issues or not, but since
the previous version of the code was not very strict on this matter, it was
determined that this issue should be addressed.
Furthermore, gamma correction feature for DVP (Digital Video Port) will now be
turned off for UniChrome Pro and Chrome 9 graphics.
