    This patch adds three devices to qemu:
    	Intel HD Audio Controller, the PCI device.  Provides a HDA bus.
    	Emulates ICH6 at the moment.  Adding a ICH9 PCIE
    	variant shouldn't be hard.
    	HDA Codec.  Attaches to the HDA bus.  Supports 16bit stereo,
    	rates 16k -> 96k, playback, recording and volume control
    	(with CONFIG_MIXEMU=y).
    	HDA Codec without recording support.  Subset of the hda-duplex
    	codec.  Use this if you don't want your guests access your mic.
    Usage: add '-device intel-hda -device hda-duplex' to your command line.
    Tested guests:
     * Linux works.
     * Win7 works.
     * DOS (mpxplay) works.
     * WinXP doesn't work.
    [ v2 changes ]
     * Fixed endianess, big endian hosts work now.
     * Fixed some emulation bugs.
     * Added immediate command emulation.
     * Added vmstate support.
     * Make it behave like all other sound card drivers:
       - can be configured via '--audio-card-list=hda'
       - can be added to a VM using '-soundhw hda'
     * Code style fixups.
     * Zapped guest-triggerable asserts.
     * Handle partial reads/writes of audio data correctly.
