devtools/cocci: add script for ethdev namespace change

The cocci script is to help add prefix 'RTE_ETH' namespace to enum
& macro of ethdev library. It helps in automating these changes for
applications. The script won't make changes in the code comment part.
Usage: spatch <script path> <app path>
