arm64: dts: ti: k3-am62: Add cpsw-mac-efuse node to wkup_conf 



The WKUP system controller address region contains an eFuse block with
MAC addresses to be used by the Ethernet controller. 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.
