watchdog: Add MOXA ART watchdog driver

Browse source 
This patch adds a watchdog driver for the main hardware watchdog timer
found on MOXA ART SoCs.

The MOXA ART SoC provides one writable timer register, restarting
the hardware once it reaches zero. The register is auto decremented
every APB clock cycle.

Required properties:
- compatible : Must be "moxa,moxart-watchdog"
- reg : Should contain registers location and length
- clocks : Should contain phandle for the clock that drives the counter
Example:

compatible = "moxa,moxart-watchdog";
reg = <0x98500000 0x10>;
clocks = <&coreclk>;
};
