In the past it was actually called i915_gpu_idle().

It evolved from that as that isn't very clear what it actually does, and
predated GEM (i.e. it also dealt with DRI1). I like having the "wait" in
the name, as that should make the might_sleep() very clear and ties in
nicely with passing around the wait-flags.

i915_gem_wait_for_idle() is still my favourite, yet.
