dev_printk(): constify the `dev' argument

Browse Source 
Add const markings to dev_name and dev_driver_string to make it clear that
dev_printk doesn't modify dev.  This is a prerequisite to adding more
const markings to other functions make it clearer, which functions can
modify dev and which can't.
