boards: silabs: Add xgm240_rb4316a and xgm240_rb4317a
Add support for xGM240-RB4316A and xGM240-RB4317A radio boards for xGM240 modules. The two boards share pinout configuration, but have different radio and power configurations. Signed-off-by: Aksel Skauge Mellbye <[email protected]>

The `xGM240P +10 dBm Module Radio Board`_ for the xGM240P module contains a Wireless
7+
System-On-Chip from the EFR32MG24 family built on an ARM Cortex®-M33 processor with excellent low
8+
power capabilities.
9+
10+
The radio board plugs into the Wireless Pro Kit Mainboard BRD4002A and is supported in Zephyr as one
11+
of several :ref:`silabs_radio_boards`.

System Clock
50+
============
51+
52+
The MGM240P module is configured to use the HFRCODPLL oscillator at 78 MHz as the system clock,
53+
locked to the 39 MHz external crystal oscillator on the board.
54+
55+
Serial Port
56+
===========
57+
58+
The MGM240P module has one USART and two EUSARTs.
59+
USART0 is connected to the board controller and is used for the console.
60+
61+
Buttons and LEDs
62+
================
63+
64+
This board has two buttons and two LEDs that share GPIO pins. If an application wants to use both
65+
a button and a LED with the same number (e.g. button 0 and LED 0), it needs to time multiplex the
66+
two functions.

75+
76+
Connect the BRD4002A board with a mounted BRD4186C radio board to your host
77+
computer using the USB port.
78+
79+
Here is an example for the :zephyr:code-sample:`hello_world` application.
80+
81+
.. zephyr-app-commands::
82+
:zephyr-app: samples/hello_world
83+
:board: xgm240_rb4316a
84+
:goals: flash
85+
86+
Open a serial terminal (minicom, putty, etc.) with the following settings:
87+
88+
- Speed: 115200
89+
- Data: 8 bits
90+
- Parity: None
91+
- Stop bits: 1
92+
93+
Reset the board and you should see the following message in the terminal:
94+
95+
.. code-block:: console
96+
97+
Hello World! xgm240_rb4316a
98+
99+
Bluetooth
100+
=========
101+
102+
To use Bluetooth functionality, run the command below to retrieve necessary binary
103+
blobs from the Silicon Labs HAL repository.
104+
105+
.. code-block:: console
106+
107+
west blobs fetch hal_silabs
108+
109+
Then build the Zephyr kernel and a Bluetooth sample with the following
110+
command. The :zephyr:code-sample:`bluetooth_observer` sample application is used in
111+
this example.
112+
113+
