dm: Tidy up four minor code nits
There is a spelling mistake and two functions are missing comments altogether. Also the flags declaration is correct, but doesn't follow style. Finally, the uclass_get_device() function has some errors in its documentation. Fix these problems. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de>
