Because this patch eliminates the mode which has a high pixel clock, probably
it can't meet Rod's requirement. 

Actually Rod wants to use reduced timing while mode is 1600x1200. 

Before, I clamped the pixel clock to 135Mhz in mode probe function, and this
patch will decrease the refresh rate because pixel clock gets lower, for
instance, 1600x1200 at 60Hz, pixel clock is 162M, when fresh rate is 50.9Hz, the
pixel clock get 135Mhz, but this fresh rate (50.9Hz) may not be supported by
all monitors, although a handy DELL monitor can support it.
