dm: core: Correct the return value for uclass_find_first_device()
This function returns -ENODEV when there is no device. This is inconsistent with other functions, such as uclass_find_next_device(), which returns 0. Update it and tidy up the incorrect '-1' values in the comments. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>
