Subject: drm/i915/audio: Hook up component bindings even if displays are
 disabled
Git-commit: 35a5fd9ebfa93758ca579e30f337b6c9126d995b
Patch-mainline: v4.20-rc1
References: bsc#1113722

If the display has been disabled by modparam, we still want to connect
together the HW bits and bobs with the associated drivers so that we can
continue to manage their runtime power gating.

Fixes: 108109444ff6 ("drm/i915: Check num_pipes before initializing audio component")
