[Intel-gfx] [PATCH 07/10] drm/i915: Convert for_each_intel_crtc_mask() to take a pipe mask instead

[Ville Syrjala <ville.syrjala@linux.intel.com>]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Often using pipes is more convenient than crtc indices.
Convert the current for_each_intel_crtc_mask() to take a
pipe mask instead of a crtc index mask, and rename it to
for_each_intel_crtc_in_pipe_mask() to make it clear what
it does.

The current users of for_each_intel_crtc_mask() don't really
care which kind of mask we use, but for other uses a pipe
mask if better.
