[dpdk-stable] [18.11 3/7] eal: remove legacy PMD log macro

[Kevin Traynor]

From: Stephen Hemminger <stephen at networkplumber.org>

[ upstream commit e7d798172f911b1af74f3c54ef67e8bb18b36284 ]

The RTE_PMD_DEBUG_TRACE was only enabled for EVENTDEV_DEBUG and
that configuration is now handled by RTE_EDEV_LOG macros.
