The VAR-SOM-MX8MN currently integrates the NXP IW61x wireless module,
providing WiFi over SDIO and Bluetooth over UART.
Move the wireless module configuration out of the base
imx8mn-var-som.dtsi and provide dedicated variant includes.
The IW61x configuration is moved to imx8mn-var-som-wifi-bt-iw61x.dtsi
and used by the Symphony evaluation board device tree.
A separate imx8mn-var-som-wifi-brcm-legacy.dtsi include is added to keep
the configuration for the legacy Broadcom SDIO WiFi module used on
earlier SOM revisions.
To preserve compatibility with older SOM revisions, add a separate
imx8mn-var-som-symphony-legacy.dtb, which disables the IW61x setup and
applies the Broadcom-specific configuration.
The Broadcom-based SOM revision is no longer in production, but support
is kept for existing users.
This keeps the VAR-SOM-MX8MN support aligned with the existing
VAR-SOM-MX8MM implementation.

The PHY LED signals originate on the SOM, but the actual LEDs are part

Wake-on-LAN via magic packet is not supported at the VAR-SOM level and

as well as an EIRQ register window for external interrupt configuration.
The driver supports both legacy pinctrl-only DTs and
