While at it, also extract a common helper to copy the timings from the
cpu transcoder to the pch transcoder. That way it's really explicit
how the lpt transcoder is hardcoded.
v2:
- Re-align #defines properly (Paulo).
- Use cpu_transcoder when copying pipe timings (Paulo).
- s/intel_pch_transcoder_enable/intel_pch_transcoder_set_timings/
since we already have a pch transcoder enable function, and this is
clearer, too.
- Fixup 80 char line overflow in intel_display.c. I've opted to ignore
this in i915_reg.h and i915_ums.c since meh.
