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. The downstream Kernel also does not have this check, so drop it to allow for more display resolutions.
