A couple of rapidio deadcoding patches. The first of these is a repost and was originally posted almost a year ago https://lore.kernel.org/all/20240528002515.211366-1-linux@treblig.org/ but got no answer. Other than being rebased and a typo fixed, it's not changed. This patch (of 2): '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.
