Replace SFP (J5) with RJ-45 connector and Ethernet PHY with Wake-on-LAN and pattern matching.
RJ-45 shall be connected through the Ethernet PHY (LAN8831) to PS of Zynq US+
The idea is that DI/OT will be always connected to Ethernet for management and slow control. Then connecting RJ-45 to PS allows us to always have connection to the platform even if PL is not programmed. However, VCOs required for WR stayed, which means if somebody needs to receive WR synchronisation it's enough to add an FMC with SFP to the System Board.
TODO: define assignment of GPIO of Ethernet PHY to power cycle circuit (Hard reset).
