The LPE audio is a child device of i915, it is powered up and down
alongside the igfx and presents no independent runtime interface. This
aptly fulfils the description of a "No-Callback" Device, so mark it
thus.
Fixes: 183c00350ccd ("drm/i915: Fix runtime PM for LPE audio")
Testcase: igt/pm_rpm/basic-pci-d3-state
