arm64: versal-net: Add support for Versal NET platform
Versal NET platform is based on Versal chip which is reusing a lot of IPs.
For more information about new IPs please take a look at DT which describe
currently supported devices.
The patch is adding architecture and board support with soc detection
algorithm. Generic setting should be very similar to Versal but it will
likely diverge in longer run.
