We can make use of serdev drivers to do simple device drivers for

of TS 27.010 with serdev drivers.

So far this has been tested with Motorola droid4 where there is a custom
packet numbering protocol on top of TS 27.010 for the MDM6600 modem.

I initially though about adding the serdev support into a separate file,
but that will take some refactoring of n_gsm.c. And I'd like to have
things working first. Then later on we might want to consider splitting
n_gsm.c into three pieces for core, tty and serdev parts. And then maybe
the serdev related parts can be just moved to live under something like
drivers/tty/serdev/protocol/ngsm.c.
