gma pipe_setup: Untangle pipe and transcoder config

Intel's manuals became much more clear with the years about what be-
longs to the transcoder and what to the pipe setup.

Although the transcoder is generally tied to a specific pipe, we
keep the naming of transcoder A, B, C which are mapped to the Primary,
Secondary, and Tertiary pipe respectively (with the exception of the
Haswell+ EDP transcoder which can be attached to any pipe).
