dt-bindings: watchdog: convert meson-wdt.txt to dt-schema

Browse Source 
Convert the Amlogic Meson6 SoCs Watchdog timer bindings to dt-schema.

Take in account the used interrupts property.

The "amlogic,meson8-wdt" representation has been simplified
since there's no users of this compatible used along the
"amlogic,meson6-wdt".

Meson SoCs Watchdog timer
Required properties:
- compatible : depending on the SoC this should be one of:
"amlogic,meson6-wdt" on Meson6 SoCs
"amlogic,meson8-wdt" and "amlogic,meson6-wdt" on Meson8 SoCs
"amlogic,meson8b-wdt" on Meson8b SoCs
"amlogic,meson8m2-wdt" and "amlogic,meson8b-wdt" on Meson8m2 SoCs
- reg : Specifies base physical address and size of the registers.
Optional properties:
- timeout-sec: contains the watchdog timeout in seconds.
Example:
wdt: watchdog@c1109900 {
compatible = "amlogic,meson6-wdt";
reg = <0xc1109900 0x8>;
timeout-sec = <10>;
};
