Adding NXP DPAA2 architecture specific mempool support

I guess this is a typo, but this prevents DPAA2_COMMON to be compiled !!
It should be 'ifeq' rather than 'ifneq'. And it will prevent COMMON
compilation only if CONFIG_RTE_LIBRTE_FSLMC_BUS=n which is not the case
right now.
We will fix it.

This dependeny doesn not looks correct, there is no folder like that.
This is something even I need to understand. From the DEPDIRS what I
understood was that though it refers to a directory, it essentially
links libraries in build/lib/*.
Further, somehow the development is deploying drivers/bus,
drivers/common and drivers/pool in lib/* under the name specified as
LIB in Makefile. My understanding was that it is expected behavior and
not special because of drivers folder.
Thus, above line only links lib/librte_common_dpaa2_qbman generated by
drivers/common/dpaa2/qbman code.
In fact, I think, this might also one of the issues why a parallel
shared build fails for DPAA2 PMD (added in Cover letter).
The dependency graph cannot create a graph for drivers/common
as dependency for drivers/net or drivers/bus and hence parallel build
fails because of missing libraries which are being parallely compiled.
