Jiri Slaby (SUSE) d52b761e4b kfifo: add kfifo_dma_out_prepare_mapped()
When the kfifo buffer is already dma-mapped, one cannot use the kfifo
API to fill in an SG list.

Add kfifo_dma_in_prepare_mapped() which allows exactly this. A mapped
dma_addr_t is passed and it is filled into provided sgl too. Including
the dma_len.
