tty: n_gsm: Add copy_config() and gsm_config() to prepare for serdev

For supporting serdev drivers, we need to be able to configure n_gsm
from drivers. Let's prepare for that by adding copy_config() and
gsm_config() helper functions by moving the code around a bit.

Let's also unify the comments to keep checkpatch happy while at it.
