rapidio: remove some dead defines

Browse Source 
Patch series "rapidio deadcoding".

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 e8de370188 ("rapidio: add mport char device
driver") but never used.

'rio_cm_work' was unused since the original commit b6e8d4aa11 ("rapidio:
add RapidIO channelized messaging driver") but never used.

Remove them.
