drm: i2c: adv7511: Restrict high pixel clock modes
Newer monitors have resolutions beyond 1080p which don't work with
the adv7511. Add a 'mode_valid' connector helper func which check if we
can support the given pixel clock or not. Use the same freq as already
done for the encoder's mode_valid() helper when the chip is set up as
a slave encoder.
