[dpdk-dev] [PATCH v2] crypto/aesni_gcm: add dynamic logging

[Naga Suresh Somarowthu]

From: Chaitanya Babu Talluri <tallurix.chaitanya.babu at intel.com>

1.added new logtype for aesni_gcm driver.
2.registered new logtype.
3.GCM_LOG_ERR and CDEV_LOG_ERR are replaced with
  new logtype name AESNI_GCM_PMD_LOG.
