Added dma_sync_single_range_for_cpu/device to dma-mapping.h in asm-avr32 to
call dma_sync_single_for_cpu/device.  This patch enables b44 to compile on
systems with these cpus.  This patch was created with the assumption that
another method of dma_sync_single_range_for_cpu/device does not exist on these
architectures.
