Add device tree bindings document for renesas-reset driver. This driver uses the WDT hardware to issue an immediate reset.

Please drop "reset", as this is a watchdog device.
+Required properties: + - compatible: must be one or more of the following: + - "renesas,r7s72100-reset" for the r7s72100 SoC + - "renesas,wdt-reset" + This is a fallback for the above renesas,*-reset entries
Please use "renesas,r7s72100-wdt". DT describes the hardware (watchdog), not the software policy (use it for reset only, as a max. timeout of 125 ms is too short for a usable watchdog).
+ - reg: base address and length of the WDT register block
+
+Example node:
+ wdt: timer@fcfe0000 {
+ compatible = "renesas,r7s72100-reset", "renesas,wdt-reset";
+ reg = <0xfcfe0000 0x6>;
+ };

when I'm talking to journalists I just say "programmer" or something like that.
