From: Jerin Jacob <jerinj at marvell.com>
Some machines may have a lot of PCI devices and all of them are
not bound to DPDK. In such case the logs from EAL creates a lot of
clutter on boot-up, typically one needs to scroll the screen to
find other issues in boot-up.
This patch changes the following to reduce the clutter in
the default boot-up logs.
- Change the log-level of PCI probes to `debug`
- Introduce new driver probe as `info` log-level for the successful probe.

- Introduce new driver probe as `info` log-level for the successful
