====================
Improve wwan qcdm compatibility with user-space tools

Historically, Qualcomm diagnostic port was a serial device, so user-space
tools were developed using tty specific features. One of the most common
tool is, for example, ModemManager libqcdm, available at
https://gitlab.freedesktop.org/mobile-broadband/ModemManager
which requires tcgetattr/tcsetattr and the possibility to get exclusive
device access to properly work.

The wwan qcdm is not really a tty device, but, besides the lack of tty
functions, it behaves as a standard serial Qualcomm diagnostic port, so,
as c230035c2f2f ("net: wwan: core: implement terminal ioctls for AT port"),
this series add support for terminal ioctls also for qcdm ports and
implement the exclusive open mode feature to improve compatibility with
user-space tools.

This is an incremental change which should not affect the existing tools
using wwan which do not rely on the implemented features.
