In the DPAA bus initialization: it builds the
device list, loads the QMAN/BMAN drivers, registers the platform mbuf
pool ops and populates the PA to VA translation table. All of it needs
the DPDK heap or a memzone for multi process scenarios.
get_iommu_class() for this bus only checks two sysfs paths, so the
initialization is not needed in scan to report the IOVA mode. Move it
back to probe.

While the change looks correct, I don't understand what is being fixed.
Could you elaborate on the issue?
In my brief discussion about this issue, I was told that some of the
these QMAN/BMAN related initialization should be done using
shared/Hugepage memory for multi-process sharing;
Hugepages are not available during scan, they become available later.
