Some support is better than none, so let's go ahead and add/use these tables when we can, and also add some logic to hdmi_port_clock_valid() to filter the modelist to just the modes we can actually support with these link rates. Hopefully we'll have a proper / non-encumbered algorithm to calculate these registers by the time we upstream and we'll be able to replace this patch with something more general purpose.
