ALSA: hda/hdmi: Disable silent stream on GLK

The silent stream stuff recurses back into i915 audio
component .get_power() from the .pin_eld_notify() hook.
On GLK this will deadlock as i915 may already be holding
the relevant modeset locks during .pin_eld_notify() and
the GLK audio vs. CDCLK workaround will try to grab the
same locks from .get_power().

Until someone comes up with a better fix just disable the
silent stream support on GLK.
