[dpdk-dev] [PATCH v2 4/5] dpaa: enable dpaax library

[Shreyansh Jain <shreyansh.jain@nxp.com>]

With this patch, dpaa bus and ethernet devices on this bus
would start using the physical-virtual library interfaces.

This patch impacts mempool/dpaa, event/dpaa and net/dpaa as
they are dependent on the bus/dpaa and thus impact linkage of
libraries.
