drm/i915: Fix enum pipe vs. enum transcoder for the PCH transcoder
Use enum pipe for PCH transcoders also in the FIFO underrun code.
Fixes the following new sparse warnings:
intel_fifo_underrun.c:340:49: warning: mixing different enum types
intel_fifo_underrun.c:340:49: int enum pipe versus
intel_fifo_underrun.c:340:49: int enum transcoder

intel_fifo_underrun.c:397:57: int enum pipe versus
intel_fifo_underrun.c:397:57: int enum transcoder
intel_fifo_underrun.c:398:17: warning: mixing different enum types
