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

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".

··· 1 - Meson SoCs Watchdog timer 2 - 3 - Required properties: 4 - 5 - - compatible : depending on the SoC this should be one of: 6 - "amlogic,meson6-wdt" on Meson6 SoCs 7 - "amlogic,meson8-wdt" and "amlogic,meson6-wdt" on Meson8 SoCs 8 - "amlogic,meson8b-wdt" on Meson8b SoCs 9 - "amlogic,meson8m2-wdt" and "amlogic,meson8b-wdt" on Meson8m2 SoCs 10 - - reg : Specifies base physical address and size of the registers. 11 - 12 - Optional properties: 13 - - timeout-sec: contains the watchdog timeout in seconds. 14 - 15 - Example: 16 - 17 - wdt: watchdog@c1109900 { 18 - compatible = "amlogic,meson6-wdt"; 19 - reg = <0xc1109900 0x8>; 20 - timeout-sec = <10>; 21 - };
