[ARM] dma-mapping: improve type-safeness of DMA translations
OMAP at least gets the return type(s) for the DMA translation functions wrong, which can lead to subtle errors. Avoid this by moving the DMA translation functions to asm/dma-mapping.h, and converting them to inline functions. Fix the OMAP DMA translation macros to use the correct argument and result types. Also, remove the unnecessary casts in dmabounce.c. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
