The driver uses the string "slcan" to populate
tty_ldisc_ops::name. Add a new macro DRV_NAME which evaluates to
"slcan" and then use DRV_NAME and to get rid on the hardcoded string
names.
Similarly, the pr_info() and pr_err() hardcoded the "slcan"
prefix. Define pr_fmt so that the "slcan" prefix gets automatically
added.

@Dario, because you are also doing a lot of changes on slcan, our
patches might conflict. Do not hesitate to take this one and add it to
your series to simplify the merge.
