Driver core: add ability for devices to create and remove bin files
Makes it easier for devices to create and remove binary attribute files so they don't have to call directly into sysfs. This is needed to help with the conversion from struct class_device to struct device. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
