The property “ti,syscon-efuse” contains a phandle to a syscon region and an offset into this region where the MAC addresses can be found. Currently "ti,syscon-efuse" points to the entire system controller address space node with an offset to the eFuse IP address. Instead add a cpsw-mac-efuse node to describe the exact eFuse area. Then point the Ethernet controller directly to this region, no offset needed. This makes it so the system controller memory area does not need to be one big syscon area, describe this bus address area as the simple-bus it is.
