LibreRouter-v1 support lacks watchdog driver

[ilario]

LibreRouter-v1 has been supported since OpenWrt 19.07 with 24463d0 by @spiccinini.
It gets shipped with LibreRouterOS 1.5 based on LibreMesh 2020.1 based on OpenWrt 19.07.

During BattleMesh v14, @T-X realized that the hardware watchdog (more details here https://gitlab.com/librerouter/watchdog-fw and here https://gitlab.com/librerouter/boards) was not interacted with by the kernel (neither when using OpenWrt 22.03.0 nor with 19.07.10) as reported here freifunk-gluon/gluon#2654, even if the instructions for that are included in the DTS file here:

openwrt/target/linux/ath79/dts/qca9558_librerouter_librerouter-v1.dts

Lines 58 to 64 in 24463d0

	watchdog {
	compatible = "linux,wdt-gpio";
	gpios = <&gpio 2 GPIO_ACTIVE_LOW>;
	hw_algo = "toggle";
	hw_margin_ms = <1000>;
	always-running;
	};

This means that during LibreRouterOS compilation some kernel modules/features are selected and these should be used also for compiling OpenWrt images for the LibreRouter-v1.
The interesting option should be one of these:

Thanks Ilario for reporting it!

I forgot to upstream this fix when I added 19.07 support to LibreRouterOs last year... https://gitlab.com/librerouter/librerouteros/-/commit/bab27e8a20bcbef4abb003c2fb416a3ec3731652

Fixed with #10859
