drm/i915/lpe: Mark LPE audio runtime pm as "no callbacks"

Browse Source 
commit 75eef0f1ed478284911b8723a5bdb659499a7aac upstream.

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")
