[dpdk-dev] [PATCH] usertools: fix pmdinfo parsing

[David Marchand]

This script was using the librte_pmd prefix has a filter to follow
DT_NEEDED entries.
Now that we changed the driver names, update this heuristic with an
explicit list of device classes.

Fixes: a20b2c01a7a1 ("build: standardize component names and defines")
