[PATCH v7 5/6] net/dpaa2: retrieve DPNI API version at init time

[Gagandeep Singh]

From: Ioana Ciornei <ioana.ciornei at nxp.com>

The list of availabla DPNI APIs depends on the DPNI API version
available on a system. Retrieve the API version in the init stage and
store it in the private structure so that it can be used at a later
stage.
