From: Shreyansh Jain <shreyansh.j...@nxp.com>
The address translation support for PA->VA is required only in
case of PA mode operation of DPDK. This was causing warning to
be reported on running any DPAA2 application in VA mode:
Add: Incorrect entry for PA->VA Table(xxxxxxxxxx)
Add: Lowest address: xxxxxxxxxxxx
This was caused by call to update the DPAAX table when VA mode
was enabled, in which case the VA==IOVA address.
