Currently there are two possible platform datas for the PXA AC97 driver: one supported by the generic AC97 driver only which provides callbacks to allow board-specific configuration at stream startup and teardown, and another for pxa2xx-ac97-lib which allows configuration of the reset GPIO for PXA2xx CPUs. Obviously this won't actually work when using the generic AC97 driver since the drivers will attempt to parse the platform data in both formats. Fix this by merging the two structures.
