drm/i915: cleanup per-pipe reg usage
We had some conversions over to the _PIPE macros, but didn't get everything. So hide the per-pipe regs with an _ (still used in a few places for legacy) and add a few _PIPE based macros, then make sure everyone uses them. [update: remove usage of non-existent no-op macro] [update 2: keep modesetting suspend/resume code, update to new reg names] Signed-off-by: Jesse Barnes <jbarnes@virtuousgeek.org> [ickle: stylistic cleanups for checkpatch and taste] Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
