Using the rte_mem_virt2iova or rte_mem_virt2phy is expensive. This library is an attempt to reduce the overall cost associated with this translation. This patch enables this dpaaX library by populating a dpaaX's table for PA to VA translation. This change will also help the caam JR driver in PA to VA translation when used with enetc driver over enetc supported SoCs.
