I added also flags for drivers constructed as you suggested (see v3).
It might however be a bit tricky to differentiate library debug flags 
form drivers, e.g.
RTE_DEBUG_MEMPOOL (library) vs RTE_DEBUG_MEMPOOL_DPAA (driver).

If there is a need the macro names can be changed by adding _LIB_ or _DRV_.
What do you think?
