drm/i915: extract intel_set_pipe_timings from crtc_mode_set

Browse source

Version 2: call intel_set_pipe_timings from both i9xx_crtc_mode_set
and ironlake_crtc_mode_set, instead of just ironlake, as requested by
Daniel Vetter.

The problem caused by calling this function from i9xx_crtc_mode_set
too is that now on i9xx we write to PIPESRC before writing to DSPSIZE
and DSPPOS. I could not find any evidence in our documentation that
this won't work, and the docs actually say the pipe registers should
be set before the plane registers.

Version 3: don't remove pipeconf bits on i9xx_crtc_mode_set.
