Add bindings for Microchip SAM9X60 Watchdog Timer

It has the same bindings as
Documentation/devicetree/bindings/watchdog/atmel-sama5d4-wdt.txt
except the compatible.

+* Microchip SAM9X60 Watchdog Timer (WDT) Controller
+
+Required properties:
+- compatible: "microchip,sam9x60-wdt"
+- reg: base physical address and length of memory mapped region.
+
+Optional properties:
+- timeout-sec: watchdog timeout value (in seconds).
+- interrupts: interrupt number to the CPU.
+- atmel,watchdog-type: should be "hardware" or "software".
+       "hardware": enable watchdog fault reset. A watchdog fault triggers
+                   watchdog reset.
+       "software": enable watchdog fault interrupt. A watchdog fault asserts
+                   watchdog interrupt.
+- atmel,idle-halt: present if you want to stop the watchdog when the CPU is
+                  in idle state.
+       CAUTION: This property should be used with care, it actually makes the
+       watchdog not counting when the CPU is in idle state, therefore the
+       watchdog reset time depends on mean CPU usage and will not reset at all
+       if the CPU stop working while it is in idle state, which is probably
+       not what you want.
+- atmel,dbg-halt: present if you want to stop the watchdog when the CPU is
+                 in debug state.
+
+Example:
+       watchdog@ffffff80 {
+               compatible = "microchip,sam9x60-wdt";
+               reg = <0xffffff80 0x24>;
+               interrupts = <1 IRQ_TYPE_LEVEL_HIGH 5>;
+               timeout-sec = <10>;
+               atmel,watchdog-type = "hardware";
+               atmel,dbg-halt;
+               atmel,idle-halt;
+       };
