[PATCH] arm64: versal-net: Add support for SPP production version
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.
