[PATCH 13/15] watchdog: orion: Add other compatibles to devicetree binding

[Ezequiel Garcia]

Add the newly supported compatible-strings for Armada 370 and Armada
XP SoC. In addition, specify the required clock inputs for each supported
compatible:
 * orion-wdt and armada-370 requires a single clock phandle
 * armada-xp requires two clock phandles with clock-names "nbclk" and "fixed".
