devices: Add an Ac97 PCI device
The Ac97 device provides the guest with an audio playback device. All input devices are stubbed out. Only playback at 48kHz is supported. The device is emulated by `Ac97Dev` which interfaces with the PCI bus. `Ac97Dev` uses `Ac97` to drive audio functions and emulate the device registers. Physical Ac97 devices consist of two parts, the bus master and a mixer. These two sets of registers are emulated by the `Ac97BusMaster` and `Ac97Mixer` structures. `Ac97BusMaster` handles audio samples and uses `Ac97Mixer` to determine the configuration of the audio backend.
