drm/i915/tgl: Clamp min_cdclk to max_cdclk_freq to unblock 8K
We still need "Bump up CDCLK" workaround otherwise getting
underruns - however currently it blocks 8K as CDCLK = Pixel rate,
in 8K case would require CDCLK to be around 1 Ghz which is not
possible.
v2: - Convert to expression(max(min_cdclk, min(pixel_rate, max_cdclk))
(Ville Syrjälä)
- Use type specific min_t, max_t(Ville Syrjälä)
