The current code uses in some instances enum transcoder for PCH
transcoders and enum pipe in others. This is error prone and clang
raises warnings like this:
drivers/gpu/drm/i915/intel_dp.c:3546:51: warning: implicit conversion
from enumeration type 'enum pipe' to different enumeration type
'enum transcoder' [-Wenum-conversion]
intel_set_pch_fifo_underrun_reporting(dev_priv, PIPE_A, false);
Consistently use the type enum pipe for PCH transcoders.

Somehow git apply-mbox could parse it, but manually applying using patch
worked. Not sure what's going on, maybe double-check it's all right.

Not sure what happened, one of the patch fragments only has one '@'
instead of two, with that fixed the patch applies.
Unfortunately the manual application missed some fragments:
drivers/gpu/drm/i915/intel_display.c:5350:51: warning: implicit
conversion from enumeration type 'enum transcoder' to different
enumeration type 'enum pipe' [-Wenum-conversion]

intel_set_pch_fifo_underrun_reporting(dev_priv, TRANSCODER_A,
What would be the best way forward from here? Revert the manual
application and apply again, or a fixup patch?
