Extended the ZynqMP and versal reset driver to support Versal NET platform,
accordingly added compatible string dt-binding for the Versal NET platform
specific.
The Versal Net device includes more security features in the platform
management controller (PMC) and increases the number of CPUs in the
application processing unit (APU) and the real-time processing unit (RPU).

Changes in V2:
- Addressed Krzysztof and Conor review comments:
- Updated the commit message [1/2] with detail description of Versal NET SoC.
- Removed the dt-bindings include versal NET header from the binding documents
as it is not used by the driver.
