Fallback to Dummy when no onboard PCH card

When the PCH card is not card 0 and device 0, fallback to dummy card to avoid sink not ready error at the framework. This ensures that the dummy card is available and completes the framework query for sink devices Tests done: Audio playback over USB Audio playback on HDMI Signed-off-by: Deepa G K <[email protected]> Tracked-On: OAM-116957 Tracked-On: OAM-116990
