Subject: [PATCH] env/dpdk: suppress EAL's RTE_LOG_INFO messages

Bump the log level for EAL to RTE_LOG_NOTICE.

Reading from rte_log.h:
```
RTE_LOG_NOTICE   6U  /**< Normal but significant condition. */
RTE_LOG_INFO     7U  /**< Informational.                    */
RTE_LOG_DEBUG    8U  /**< Debug-level messages.             */
```

We're doing this primarily for the NVMe hotplug poller,
which calls spdk_pci_enumerate() and constantly bloats
the output with logs describing which device is currently
iterated over. We don't want to see those.
