[PATCH] doc: announce DMA configuration structure changes

[pbhagavatula]

From: Pavan Nikhilesh <pbhagavatula@marvell.com>

Deprecate rte_dma_conf structure to allow for a more flexible
configuration of DMA devices.
The new structure will have a flags field instead of multiple
boolean fields for each feature.
