[PATCH AUTOSEL 5.15 08/19] ASoC: Intel: skl_hda_dsp_generic: Drop HDMI routes when HDMI is not available

[Sasha Levin]

From: Peter Ujfalusi <peter.ujfalusi@xxxxxxxxxxxxxxx>

[ Upstream commit 3d1dc8b1030df8ca0fdfd4905c88ee10db943bf8 ]

When the HDMI is not present due to disabled display support
we will use dummy codec and the HDMI routes will refer to non existent
DAPM widgets.

Trim the route list from the HDMI routes to be able to probe the card even
if the HDMI dais are not registered.
