ARM: dts: da850: specify the maximum pixel clock rate for tilcdc 

At maximum CPU frequency of 300 MHz the maximum pixel clock frequency
is 37.5 MHz[1]. We must filter out any mode for which the calculated
pixel clock rate would exceed this value.

Specify the max-pixelclock property for the display node for
da850-lcdk.
