drm/i915: Prefer encoder->name over port_name() 

enum port is a mess now because it no longer matches the spec
at all. Let's start to dig ourselves out of this hole by
reducing our reliance on port_name(). This should at least make
a bunch of debug messages a bit more sensible while we think how
to fill the the hole properly.

Based on the following cocci script with a lot of manual cleanup
(all the format strings etc.):
@@
expression E;
@@
(
- port_name(E->port)
+ E->base.base.id, E->base.name
