arm64: versal-net: Add support for SPP production version

Browse source 
Production version restarting platform version field from 0 that's why add
new calculation to be able to use different DT for these platforms.
Requested DT names for production silicons for IPP/SPP and EMU platform are
versal-net-ipp-rev2.0.dts and versal-net-emu-rev2.0.dts.
If platform version increase numbers revision can be even higher.
As of today platform version is 2 that's why expected is rev2.2.
