There are now two fsldma.h files.

drivers/dma/fsldma.h: no changes, houses the private driver 
implementation details.

arch/powerpc/include/asm/fsldma.h: adds some helper routines and 
definitions for the DMA_SLAVE capability of the driver.  It defines an 
interface for other drivers to use fsldma to initiate device-to-memory 
dma.  Any drivers that use the interface will depend on CONFIG_FSL_DMA 
hence placing this public header under arch/powerpc/include.
