AC97 Codec Core,Intel8x0 driver
This patch adds a AC97_SCAP_DETECT_BY_VENDOR flag for Xbox. If the flag
is set, the AC97 codec is detected only by reading of a reasonable
vendor ID. It seems that Xbox has accessible only vendor/device ID
registers for reading. Also, a new xbox parameter for snd-intel8x0
has been introduced to let user force this behaviour.
