eventdev: fix missing driver names in info struct

[ upstream commit cbbba8b87e03a028a2ac2f3542f1927ba4edc598 ]

Rather than relying on the individual drivers to always populated the
driver name field in the info structure - something missed by some
drivers, we can do so in the eventdev rte_event_dev_info_get() function.
This fixes issues

Fixes: bbbb929 ("event/skeleton: add skeleton eventdev driver")
Fixes: 0ce3ce7 ("event/dpaa2: add configuration functions")
