dde_bsd: ignore HDMI/DP devices (00:03:00) 

Unfortunatly, there is no support for any HDMI/DP based HDA codecs in
this driver. Therefore we try to filter out known devices (normally the
PCI device on 00:03.00). This could also be done in the platform_drv's
configuration by explicitly naming the BDF but for better or worse that
will not work when using a wildcard class like HDAUDIO which is done in
generic run scripts.

Issue #1644.
