Since intel_ddi_level() now looks at the buf_trans table there's
no point in having intel_ddi_hdmi_num_entries() around. Just
roll the necessary bits of locic into
intel_ddi_hdmi_level()/intel_ddi_level().

We use encoder->get_buf_trans() in many places, for example
intel_ddi_dp_voltage_max(), and the hook was set to some old platform's
function for DG2 SNPS PHY. Convert SNPS PHY to use the same translation
mechanisms as everything else.

Store the default HDMI buf trans entry in struct intel_ddi_buf_trans
so that it's next to the actual table. This let's us start ridding
ourselves of some platofrm specifics in intel_ddi_hdmi_num_entries().

Put a wrapper struct around the buf trans tables so that
we can declare the number of entries and default HDMI entry
alongside the table.

Define and use DP voltage swing and pre-emphasis translation tables
for ADL-P.
v2:
- Update according to recent bspec updates; there are now separate
tables for RBR/HBR and HBR2/HBR3. (Anusha)

Ville suggested this, these tables are probably better being
standalone.
This fixes up the cnl/bxt interfaces to be like the others,
the intel one I left alone since it has a few extra entrypoints.
v2: add back missing rocketlake bits.
