dt-bindings: watchdog: re-order entries to match coding convention

The Devicetree bindings coding convention, as used in most of the files
and expressed in Documentation/devicetree/bindings/example-schema.yaml,
expects:
1. "allOf:" block just before "properties:" (or after "required:" for
more complex cases),
2. additionalProperties/unevaluatedProperties at the end of the file,
just before the examples section.

Re-order few schemas to match the convention to avoid repeating review
comments for new patches using existing code as template. No functional
changes.

dt-bindings: watchdog: indentation, quotes and white-space cleanup

Minor cleanup without functional impact:
1. Indent DTS examples to preferred four-spaces (more readable for DTS),
2. Drop unneeded quotes,
3. Add/drop blank lines to make the code readable.

The watchdog compatible strings are suppose to be SoC orientated.
In the more recently added Rockchip SoC dtsi files only

compatible strings:

"rockchip,px30-wdt", "snps,dw-wdt"
"rockchip,rk3228-wdt", "snps,dw-wdt"
"rockchip,rk3308-wdt", "snps,dw-wdt"

In case if DW Watchdog IP core is built with WDT_USE_FIX_TOP == false,
a custom timeout periods are used to preset the timer counter. In
this case that periods should be specified in a new "snps,watchdog-tops"
property of the DW watchdog dts node.

dt-bindings: watchdog: dw-wdt: Support devices with asynch clocks

DW Watchdog IP core can be synthesised with asynchronous timer/APB
clocks support (WDT_ASYNC_CLK_MODE_ENABLE == 1). In this case
separate clock signals are supposed to be used to feed watchdog timer
and APB interface of the device. Let's update the DW Watchdog DT node
schema so it would support the optional APB3 bus clock specified along
with the mandatory watchdog timer reference clock.

dt-bindings: watchdog: Convert DW WDT binding to DT schema

Modern device tree bindings are supposed to be created as YAML-files
in accordance with dt-schema. This commit replaces the DW Watchdog
legacy bare text bindings with YAML file. As before the binding states
that the corresponding dts node is supposed to have a registers
range, a watchdog timer references clock source, optional reset line and
pre-timeout interrupt.
