OMAPDSS: DPI: Fix wrong pixel clock limit
DPI is supposed to skip odd dividers in the clock path when the pixel clock is higher than 100MHz. The code, however, defines the pixel clock limit as 1MHz. This causes the driver to skip valid clock dividers, possibly making the pixel clock to be further away from the requested one than necessary. Fix the clock limit to 100MHz.
