Move the iop32x specific definitions into drivers/dma/iop-adma.h and the platform_data into include/linux/platform_data/dma-iop32x.h, and change the machine code to no longer reference those. The DMA0_ID/DMA1_ID/AAU_ID macros are required as part of the platform data interface and still need to be visible, so move those from one header to the other.
