Russell King 8c8a0ec57e [ARM] dma: use new dmabounce_sync_for_xxx() for dma_sync_single_xxx()

Russell King 56f55f8b58 [ARM] dma: provide a better dma_map_page() implementation 
We can translate a struct page directly to a DMA address using
page_to_dma().  No need to use page_address() followed by
virt_to_dma().

Russell King 9dd4286805 [ARM] dma-mapping: provide sync_range APIs 
Convert the existing dma_sync_single_for_* APIs to the new range based
APIs, and make the dma_sync_single_for_* API a superset of it.

Russell King 98ed7d4b1a [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.
