This extends the device tree bindings for the Faraday FTWDT010
block to cover:
- The "moxa,moxart-watchdog" compatible version
- The "aspeed,ast2400-wdt" and "aspeed,ast2500-wdt" versions
- clocks (PCLK non-optional, the Gemini also have this now)
- reset line (optional, exist on the Gemini)
- configuration to use the external clock (faraday,use-extclk)

Faraday Technology FTWDT010 watchdog
This is an IP part from Faraday Technology found in the Gemini
-SoCs and others.
+and MOXA ART SoCs and others.
Required properties:
- compatible : must be one of
"faraday,ftwdt010"
"cortina,gemini-watchdog", "faraday,ftwdt010"
+ "moxa,moxart-watchdog", "faraday,ftwdt010"
+ "aspeed,ast2400-wdt", "faraday,ftwdt010"
+ "aspeed,ast2500-wdt", "faraday,ftwdt010"
- reg : shall contain base register location and length
-- interrupts : shall contain the interrupt for the watchdog
+- clocks : the clock driving the IP block (PCLK) and optionally
+ an external clock (EXTCLK)
+- clock-names : should be "PCLK" for the IP block clock and
+ "EXTCLK" for the external clock if present
Optional properties:
+- interrupts : the bark interrupt for the watchdog
+- resets : reset line for the IP block
- timeout-sec : the default watchdog timeout in seconds.
+- faraday,use-extclk : if set, the "EXTCLK" provided in the clocks
+ property will be used to clock the watchdog
