[PATCH v2] devtools/cocci: added script for ethdev namespace

[Aman Singh]

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>

v2:
* Added support for struct changes
* Removed backward compatibility code gen part
