From: "Dr. David Alan Gilbert" <linux@treblig.org>

'mport_dma_buf', 'rio_mport_dma_map' and 'MPORT_MAX_DMA_BUFS' were
added in the original
commit e8de370188d0 ("rapidio: add mport char device driver")
but never used.

'rio_cm_work' was unused since the original
commit b6e8d4aa1110 ("rapidio: add RapidIO channelized messaging
driver")
but never used.

Remove them.
