drm/nouveau: Runtime suspend despite HDA being unbound
Commit 5addcf0a5f0f ("nouveau: add runtime PM support (v0.9)") prevents
runtime suspend of the GPU if its integrated HDA controller is not bound
to a driver. The rationale appears to be that probing the HDA fails if
the GPU is in D3cold.
However we now use a device link to ensure that the GPU is runtime
resumed while the HDA controller is probed, rendering this safety
measure obsolete. Remove it.
