[PATCH] Driver core: add macros notice(), dev_notice()

Both usb.h and device.h have collections of convenience macros for
printk() with the KERN_ERR, KERN_WARNING, and KERN_NOTICE severity
levels. This patch adds macros for the KERN_NOTICE level which was
so far uncatered for.

These macros already exist privately in drivers/isdn/gigaset/gigaset.h
(currently in the process of being submitted for the kernel tree)
but they really belong with their brothers and sisters in
include/linux/{device,usb}.h.
