rapidio: remove unused functions
rio_request_dma() and rio_dma_prep_slave_sg() were added in 2012 by commit
e42d98ebe7d7 ("rapidio: add DMA engine support for RIO data transfers")
but never used.
rio_find_mport() last use was removed in 2013 by commit 9edbc30b434f
("rapidio: update enumerator registration mechanism")
rio_unregister_scan() was added in 2013 by commit a11650e11093 ("rapidio:
make enumeration/discovery configurable") but never used.
Remove them.
