Ralink RT2880 Watchdog bindings used text format, so migrate them to YAML.
There are some additions to the binding that were not in the original
txt file. This binding is used in RT2880, RT3050, RT3352, RT3883, RT5350,
and MT7620 SoCs. To properly match all dts nodes included in openWRT git
trees we need to add to the schema 'reset' and 'reset-names'. 'reset-names'
property is always string 'wdt' so maintain that as const in the schema.

Changes in v2:
 - Fix reg address and size in example.
