[PATCH] Pass struct dev pointer to dma_cache_sync()

Pass struct dev pointer to dma_cache_sync()

dma_cache_sync() is ill-designed in that it does not have a struct device
pointer argument which makes proper support for systems that consist of a
mix of coherent and non-coherent DMA devices hard.  Change dma_cache_sync
to take a struct device pointer as first argument and fix all its callers
to pass it.
