Why the i915 driver gets initialized *so late*?

Maybe, because it’s built as a module?

$ grep I915 /boot/config-4.20.8.mx64.245 
CONFIG_DRM_I915=m
# CONFIG_DRM_I915_ALPHA_SUPPORT is not set
CONFIG_DRM_I915_CAPTURE_ERROR=y
CONFIG_DRM_I915_COMPRESS_ERROR=y
CONFIG_DRM_I915_USERPTR=y
# CONFIG_DRM_I915_GVT is not set
CONFIG_SND_HDA_I915=y

That explains. You built the HD-audio as built-in while the graphics as module. This makes the binding impossible at the time of sound driver initialization.

If you build the graphics driver as a module, built the sound driver also as a module.
