drm/i915: convert PIPE_CLK_SEL to transcoder

This register appeared in Haswell. It does not have an EDP version
because the EDP transcoder is always tied to the DDIA clock. Notice
that if we call PIPE_CLK_SEL(pipe) when pipe is PIPE_A and transcoder
is TRANSCODER_EDP we might introduce a bug, that's why this is a
transcoder register even though it does not have an EDP version.

Even though Haswell names this register PIPE_CLK_SEL, it will be
renamed to TRANS_CLK_SEL in the future, so let's just start using the
real name that makes more sense and avoids misusage.
