[dpdk-dev] [PATCH v4 1/3] ethdev: move log macro to header

[Ferruh Yigit]

Macro moved to header to be able to convert logging usage in header.
And since it has been moved to public header changed naming and added
RTE prefix, ethdev_log -> RTE_ETHDEV_LOG

Also need to add logtype variable to map file since logging macro used
from other libraries.

v2:
* updated commit log

v3: no update

v4:
* rename logtype variable to rte_eth_dev_logtype
* add logtype variable to .map file
