[PATCH v2025.09.y 26/58] common: tlv: fix link error when CONFIG_NET is disabled

[Ahmad Fatoum]

ethaddr_list and eth_of_get_fixup_node are used unconditionally in
of_tlv_fixup, but there is no dependency on CONFIG_NET for CONFIG_TLV.

Turn the ethernet-related fixup code into dead code if CONFIG_NET is
disabled and emit a warning to fix this.

(cherry picked from commit 53c72e610a314fc4a9a133e2615f0bc88af9df28)
