Benjamin Lindqvist 54cb2bcd41 drivers: modem: gsm_ppp: Enable start/stop 
These changes enable applications to restart the networking stack which
was previously not possible without rebooting the device. This was a
major show-stopper because it made power management impossible, and
furthermore made it impossible to recover from a bad modem state without
rebooting.

This has been verified to work on a SIMCOM7600E modem, both with and
without CONFIG_GSM_MUX enabled.

Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers 
Now that device_api attribute is unmodified at runtime, as well as all
the other attributes, it is possible to switch all device driver
instance to be constant.

A coccinelle rule is used for this:

@r_const_dev_1
  disable optional_qualifier
@
@@
-struct device *
+const struct device *

@r_const_dev_2
 disable optional_qualifier
@
@@
-struct device * const
+const struct device *

Fixes #27399

Jukka Rissanen 492088b3fa net: ppp: Convert PPP driver to use normal UART APIs 
This is needed so that we can support GSM 07.10 muxing protocol.

Jukka Rissanen b5525a0f91 drivers: gsm_mux: Support GSM 07.10 muxing protocol 
Add support to GSM 07.10 muxing protocol which is used to
share the same UART for PPP and AT commands among other things.
This allows e.g., the modem to send SMS and have PPP connection
active at the same time.
