drm/i915: Use macros to switch between equivalent pipe registers
The purpose is to make the code much easier to read and therefore reduce the possibility for bugs. A side effect is that it also makes it much easier for the compiler, reducing the object size by 4k -- from just a few functions! Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
