Instead of adding one more dependency I think we can cleanup this 
dependency list. Similar changes done in ethernet subsystem. Please 
have a look at below commits:

e8b6c54f6d57 net: xilinx: temac: Relax Kconfig dependencies
d7eaf962a90b net: axienet: In kconfig remove arch dependency for axi_emac
