[PATCH] devtools: add .clang-format file

[Abdullah Ömer Yamaç]

clang-format is a tool to format C/C++/Objective-C code. It can be used
to reformat code to match a given coding style, or to ensure that code
adheres to a specific coding style. It helps to maintain a consistent
coding style across the DPDK codebase.

.clang-format file overrides the default style options provided by
clang-format and large set of IDEs and text editors support it.
