intel-hda: fix codec addressing.

The HDA bus supports up to 15 codecs, with addresses 0 ... 14.
We get that wrong in two places:

  • When handing out addresses we accept address 15 as valid.
  • The bitmasks for two registers (WAKEEN and STATESTS) don't
    have bit 14 set....

intel-hda: Honor WAKEEN bits.

HDA: Honor WAKEEN bits when deciding to raise an interrupt on codec
status change. This prevents an interrupt storm with the Haiku HDA
driver which does not handle codec status changes in the irq handler.

intel-hda: exit cleanup

Add pci exit callback for the intel-hda device and cleanup properly.
Also add an exit callback to the HDA bus implementation and make sure
it is called on qdev_free().

Add Intel HD Audio support to qemu.

This patch adds three devices to qemu:

intel-hda
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-duplex
HDA Codec. Attaches to the HDA bus. Supports 16bit stereo,...
