[Intel-gfx] [CI 29/62] drm/i915: Convert wait_for(I915_READ(reg)) to intel_wait_for_register()

[Chris Wilson]

By using the out-of-line intel_wait_for_register() not only do we can
efficiency from using the hybrid wait_for() contained within, but we
avoid code bloat from the numerous inlined loops, in total (all patches):
