I classed this as part of the i915 GEM uapi facing code, so i915_gem.
The principal caller of the wakeref pm is i915_gem_execbuffer, but it
looked a bit lonely by itself so I added the suspend/runtime.

However, this code is a bit mixed in terms of functionality between high
level GEM ops and lower level interaction with HW, so I expect some
refinement in future. The low level stuff will have intel_foo as it
principally interacts with the HW (with i915_gem callers for the most
part, and with i915_shiny callers if we house a new uapi).
