apps/examples/lvgldemo: Fix up some include paths
apps/examples/lvgldemo: The last final now conforms to the NuttX coding style.
apps/graphics/littlevgl: Two more files are closer to the NuttX coding style.
apps/graphics/littlevgl: Two more files are closer to the NuttX coding style.
apps/examples/lvgldemo: Three more files are closer to the NuttX coding style.
apps/examples/lvgldemo: Two more files are closer to the NuttX coding style.
apps/examples/lvgldemo: Two more files are closer to the NuttX coding style.
Add include/graphics/.gitignore
apps/include/graphics: Remove lvgl.h. graphics/littlevgl/Makefile now copies the file into position.
apps/graphics/littlevgl: Add .gitignore file
apps/graphics/littlevgl: Most of these files follow the coding style now.
apps/graphics/littlevgl: This gets a couple of files closer to the NuttX coding style.
apps/examples/lvgldemo: Add lvgldemo example
apps/graphics/littlevgl: Add littlevgl library
