There is no reason to setup ROM source if read_rom_hwaddr hook doesn't exist or reading mac address fails. It is ending up with confusion about mac address source.

It is nicely visible if you put mac address to DT as local-mac-address = [ff ff ff ff ff ff]; but also save ethaddr to variables setenv -f ethaddr 02:18:31:7e:3e:01

Before this patch U-Boot prints that source is DT Address in ROM is ff:ff:ff:ff:ff:ff Address in environment is 02:18:31:7e:3e:01

After that source is DT: Address in DT is ff:ff:ff:ff:ff:ff Address in environment is 02:18:31:7e:3e:01
