[dpdk-dev] [PATCH v1 3/4] eal/memory: rename memory translational api to _iova types

[Santosh Shukla <santosh.shukla@caviumnetworks.com>]

The following api renamed from:

rte_mempool_populate_phys()
rte_mempool_populate_phys_tab()
rte_eal_using_phys_addrs()
rte_mem_virt2phy()
rte_dump_physmem_layout()
rte_eal_get_physmem_layout()
rte_eal_get_physmem_size()
rte_malloc_virt2phy()
rte_mem_phy2mch()

To the following iova types api:

rte_mempool_populate_iova()
rte_mempool_populate_iova_tab()
rte_eal_using_iova_addrs()
rte_mem_virt2iova()
rte_dump_iovamem_layout()
rte_eal_get_iovamem_layout()
rte_eal_get_iovamem_size()
rte_malloc_virt2iova()
rte_mem_phy2iova()
