[PATCH v2] doc: announce changes to dma device structures

[Amit Prakash Shukla <amitprakashs@marvell.com>]

A new flag ``RTE_DMA_CAPA_QOS`` will be introduced to advertise dma device's QoS
capability. In order to support the parameters for this flag, new fields will be
added in ``rte_dma_info`` and ``rte_dma_conf`` structures to get device supported
priority levels and to configure the required priority level.
