boards: silabs: Consistently name radio boards

Rename all Silicon Labs radio boards to always use the official kit name of
the kit containing only the radio board as board target name. Disentangle
boards using Series 1 and Series 2 SoCs that have almost nothing in common
in terms of devicetree content, but still occupied the same directory.

As part of the initial HWMv2 port, all radio boards were merged into a
single target efr32_radio, using the SoC as a board qualifier to target
specific boards. This was unfortunate, as the SoC name is not sufficient
to identify a specific board -- the same SoC may be used on multiple
different boards. This commit reinstates every radio board as an individual
board target.

+Overview
+********
+
+Radio Boards are used together with a Wireless Mainboard, which is a
+development platform for application development and debugging of wireless
+products.
+
+There are two main variants of the Mainboard:
+
+- Wireless Starter Kit Mainboard (board BRD4001A, available standalone as SLWMB4001A)
+- Wireless Pro Kit Mainboard (board BRD4002A, available standalone as Si-MB4002A)
+
+The Wireless Pro Kit Mainboard is a strict superset of the Wireless Starter Kit,
+the two boards are pin compatible for all shared functionality.
+
+Wireless Starter Kits and Wireless Pro Kits are kits that bundle one or more
+Radio Boards with one or more Mainboards.
+
+In Zephyr, Radio Boards are used as board targets, irrespective of whether the
+board was acquired standalone or as part of a Starter Kit or Pro Kit. The kit
+name of the standalone Radio Board is used as the board target.
+

 Programming and Debugging
 *************************
 
-The BRD4001A includes an `J-Link`_ serial and debug adaptor built into the
-board. The adaptor provides:
-
-- A USB connection to the host computer, which exposes a debug interface and a
-  USB Serial Port.
-- A physical UART connection which is relayed over interface USB Serial port.
-- An Ethernet connection to support remote debugging.
-
-It is compatible with the following host debug tools:
-
-- :ref:`openocd-debug-host-tools`
-- :ref:`jlink-debug-host-tools`
-
-OpenOCD is included in the Zephyr SDK. Refer to the links above for information
-on how to install required host debug tools if you are not using the Zephyr SDK.

+System Clock
+============
+
+The EFR32MG12P SoC is configured to use the 38.4 MHz external oscillator on the
+board.
+
+Serial Port
+===========
+
+The EFR32MG12P SoC has four USARTs and one Low Energy UARTs (LEUART).
+USART0 is connected to the board controller and is used for the console.
+
+Programming and Debugging
+*************************
+
+Flashing
+========
+
+Connect the BRD4001A board with a mounted BRD4161A radio module to your host
+computer using the USB port.
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: slwrb4161a
+   :goals: flash
+
+Open a serial terminal (minicom, putty, etc.) with the following settings:
+
+- Speed: 115200
+- Data: 8 bits
+- Parity: None
+- Stop bits: 1
+
+Reset the board and you should see the following message in the terminal:

+System Clock
+============
+
+The EFR32FG1P SoC is configured to use the 38.4 MHz external oscillator on the
+board.
+
+Serial Port
+===========
+
+The EFR32FG1P SoC has two USARTs and one Low Energy UARTs (LEUART).
+USART0 is connected to the board controller and is used for the console.

+Flashing
+========
+
+Connect the BRD4001A board with a mounted BRD4250B radio module to your host
+computer using the USB port.
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::

+- Speed: 115200
+- Data: 8 bits
+- Parity: None
+- Stop bits: 1
+
+Reset the board and you should see the following message in the terminal:

+System Clock
+============
+
+The EFR32FG13P SoC is configured to use the 38.4 MHz external oscillator on the
+board.
+
+Serial Port
+===========
+
+The EFR32FG13P SoC has three USARTs and one Low Energy UARTs (LEUART).
+USART0 is connected to the board controller and is used for the console.
+
+Programming and Debugging
+*************************
+
+Flashing
+========
+
+Connect the BRD4001A board with a mounted BRD4255A radio module to your host
+computer using the USB port.
+
+Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: slwrb4255a
+   :goals: flash
+
+Open a serial terminal (minicom, putty, etc.) with the following settings:
+
+- Speed: 115200
+- Data: 8 bits
+- Parity: None
+- Stop bits: 1
+
+Reset the board and you should see the following message in the terminal:
+
+.. code-block:: console
+
+   Hello World! slwrb4255a
