samples: net: cloud: tagoio: Remove GSM modem overlay 



The gsm modem driver is deprecated and will be removed. Remove
the build overlay and dependency on the gsm modem from the
tagoio sample.

The new cellular modem driver and subsystem use the native
networking stack and the pm subsystem, so just like ethernet,
enabling the cellular modem is up to the board configuration.

Modem

=====



The Modem support is quite similar to WIFI, you need a board with an embedded

Modem support or you can add a shield.  Currently, the overlay was created to

allow modems with PPP support.  This was tested using ``SIMcom SIM808 EVB``.

Additionally you need fill ``CONFIG_MODEM_GSM_APN`` with the correspondent Access

Point Name (APN) at

:zephyr_file:`samples/net/cloud/tagoio_http_post/overlay-modem.conf` file. A

DTC overlay file should be used to configure the glue between the modem and the

uart port. It can reside at boards directory, with the board name, or it can be

a special designator like defined at ``arduino.overlay``.

In a terminal window you can check if communication is happen:



.. code-block:: console



    $ minicom -D /dev/ttyACM0
