The driver checks if the pixel clock of the given mode matches an entry
in the mpll config table. The frequencies in the mpll table are meant as
a frequency range up to which the entry works, not as a frequency that
must match the pixel clock. Return MODE_OK when the pixelclock is
smaller than one of the mpll frequencies to allow for more display
resolutions.
