This patch will adjust the setup the DMA controller for the AC97 Controller in the at32ap700x machine code. This setup matches the new ALSA driver for the AC97C. The struct ac97c_platform_data has been moved into its own header file located in the sound include path. Tested on ATSTK1006 + ATSTK1000. This patch will setup the AC97 controller properly for the adjusted machine code. Both EVKLCD10x and Hammerhead board has been updated. Tested on EVKLCD10x, and copied to Hammerhead board.
