Following changes are done as a part of cleanup: 1. Moved the platform specific `C` examples from top level examples/ directory to platform/ subdirectory and renamed helloedison.c to gpio_edison.c 2. C specific examples are moved to a new c/ subdirectory. As a part of this process, examples are modified to follow same standards and few new examples are also added. 3. Include the newly added C examples to relevant API documentation 4. Ran clang-format for all source files in c/, c++/, platform/ subdirectories Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Brendan Le Foll <brendan.le.foll@intel.com>
