drm/i915: Give DDI encoders even better names
Let's pimp the DDI encoder->name to reflect what the spec calls them. Ie. on pre-tgl DDI A-F, on tgl+ DDI A-C or DDI TC1-6. Also since each encoder is really a combination of the DDI and the PHY we include the PHY name as well. ICL is a bit special since it already has the two different types of DDIs (combo or TC) but it still calls them just DDI A-F regarless of the type. For that let's add an extra "(TC)" note to remind is which type of DDI it really is. The code is darn ugly, but not sure there's much we can do about it.
