Add the hpe gxp watchdog timer binding hpe,gxp-wdt.
This will enable support for the HPE GXP Watchdog.

Signed-off-by: Nick Hawkins <nick.hawkins@hpe.com>

v5:
* Fixed version log
v4:
* Made watchdog a child of timer because of same register
  area based on review feedback
* Simplified the watchdog yaml as it will get information
  from parent device
v3:
* Used proper patchset format.
v2:
* Converted from txt to yaml

allOf goes after maintainers, before properties.

> How is this h/w controlled? I'm guessing it's part of the timer? If so, you don't need this node. A single node can implement multiple functions.

It is associated with the timer because of the shared register set. Based on feedback from Krzysztof I need to create a child node for gxp-timer. I therefore will remove this file and move gxp-wdt to the hpe,gxp-timer.yaml as a child node.

Thank you for the feedback.
