dma: iop-adma: allow building without platform headers
Now that iop3xx and iop13xx are gone, the iop-adma driver no
longer needs to deal with incompatible register layout defined
in machine specific header files.
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.
