Piyush Mehta 737af37e9c dt-bindings: reset: Updated binding for Versal-NET reset driver
Added dt-binding documentation for Versal NET platforms.

Versal Net is a new AMD/Xilinx  SoC.

The SoC and its architecture is based on the Versal ACAP device.
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).

description: |
The Zynq UltraScale+ MPSoC and Versal has several different resets.
The PS reset subsystem is responsible for handling the external reset
input to the device and that all internal reset requirements are met
for the system (as a whole) and for the functional units.
Please also refer to reset.txt in this directory for common reset
controller binding usage. Device nodes that need access to reset
lines should specify them as a reset phandle in their corresponding
node as specified in reset.txt.
