Subject: [PATCH 1/2] samples: move blackfin gptimers-example from Documentation
Move blackfin gptimers-example to samples and remove it from Documentation
Makefile. Update samples Kconfig and Makefile to build gptimers-example.
blackfin is the last CONFIG_BUILD_DOCSRC target in Documentation/Makefile,
hence this patch also includes changes to remove CONFIG_BUILD_DOCSRC from
Makefile and lib/Kconfig.debug.
