* ``rte_mem_phy2mch`` was used in Xen dom0 to obtain the physical address;
remove this API as Xen dom0 support was removed.

+ are deprecated and have new alias with IOVA wording.**
+
+ * ``phys_addr_t`` can be often replaced by ``rte_iova_t`` of same size.
+ * ``RTE_BAD_PHYS_ADDR`` is often replaced by ``RTE_BAD_IOVA`` of same value.
+ * ``rte_memseg.phys_addr`` is aliased with ``rte_memseg.iova_addr``.
+ * ``rte_mem_virt2phy()`` can often be replaced by ``rte_mem_virt2iova``.
+ * ``rte_malloc_virt2phy`` is aliased with ``rte_malloc_virt2iova``.
