[RFC 0/2] drm/i915/display: revamped crtc iterators

[Jani Nikula]

I didn't pick the idea, the idea picked me, and I had to do this.

[RFC 1/2] drm/i915/display: add improved crtc iterators

[Jani Nikula]

The macros for iterating crtcs have become unweildy. Add a more generic
solution.

This is extensible via new initialization functions, more pipe_masks,
and dedicated .get_next() functions.
