CMI8788 audio card/chip support

[James Powell]

kldload snd_driver only detected my USB Headset and loaded theusb audio driver. It did not detect my CMI8788 (ASUS Xonar DX PCIe)and snd_cmi does not support it.

cat /dev/sndstat generated this:
FreeBSD Audio Driver (newpcm: 64bit 2009061500/amd64)Installed devices:pcm0: <USB audio> (play/rec) default
Which is my Logitech USB headset, not my PCIe sound card.
The boot generated a message stating "Unsupported Sound Carddetected. Please contact lists at support.freebsd.org with soundcard make and model."
