From: Radhakrishna Sripada <radhakrishna.sripada@intel.com>

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.

Bspec: 64568

v2: Rebasing with Clint's HDMI C10 PLL tables (Mika)

v3: Add missing use_hdmi checks from Clint's HDMI implementation changes (Ankit)
