[dpdk-dev] [PATCH v4 01/13] eal/log: introduce log register macro

[<jerinj@marvell.com>]

From: Jerin Jacob <jerinj@marvell.com>

Introducing the RTE_LOG_REGISTER macro to avoid the code duplication
in the log registration process.

It is a wrapper macro for declaring the logtype, register the log and sets
it's level in the constructor context.
