drm/i915/dp: Respect the sink's max TMDS clock when dealing with DP->HDMI DFPs

Browse source

Currently we only look at the DFPs max TMDS clock limit when
considering whether the mode is valid, or whether we can do
deep color. The sink's max TMDS clock limit may be lower than
the DFPs, so we need to account for it as well.
