  The phys_addr concept is deprecated in rte_memzone, change it to access
iova member, and use the type 'rte_iova_t'.

Also rename the rx/tx_ring_phys_addr definitions to rx/tx_ring_dma that
matches the IOVA concept design.

I found that ixgbe, i40e, iavf had used 'rz->iova' instead of 'rz->phys_addr', this was
the main reason that I changed it for ice. For the name & type, I think it may be acceptable,
need no more patches to change them.

It seems this issue also exists in other PMDs, like ixgbe, i40e, iavf..., do
you have plan to fix them all?
