[Intel-gfx] [PATCH 8/9] drm/i915/mtl: Add C10 phy programming for HDMI

Like DG2, we still don't have a proper algorithm that can be used
for calculating PHY settings, but we do have tables of register
values for a handful of the more common link rates. 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.
