Merge branch 'can327-CAN-ldisc-driver-for-ELM327-based-OBD-II-adapters'

Max Staudt says:
====================
This is the can327 driver. It does a surprisingly good job at turning
ELM327 based OBD-II interfaces into cheap CAN interfaces for simple
homebrew projects.

Please see the included documentation for details and limitations:
Documentation/networking/device_drivers/can/can327.rst
