drm/i915: Split the crtc_mode_set function along HAS_PCH_SPLIT() lines.

This path, which shouldn't be *that* complicated, is now so littered with per-chipset tweaks that it's hard to trace the order of what happens. HAS_PCH_SPLIT() is the most radical change across chipsets, so it seems like a natural split to simplify the code. This first commit just copies the existing code without changing anything. v2: updated to track removal of call to intel_enable_plane from i9xx_crtc_mode_set Signed-off-by: Eric Anholt <[email protected]> Hella-acked-by: Jesse Barnes <[email protected]> Signed-off-by: Chris Wilson <[email protected]>
