sound: Add PCI device IDs for LynxPoint HDA

Add device IDs for LynxPoint-H and LynxPoint-LP for
the HDA sound driver.

BUG=chrome-os-partner:21216
BRANCH=falco
TEST=emerge-falco depthcharge

Note that this by itself it not enough to make it beep,
there still needs to be a beep verb table and possibly
some additional tweaks to depthcharge driver since it
expects some link-specific verb entries.

However with this change it no longer complains that it
cannot find the audio controller:
Audio: Controller not found!
