[PATCH] ramips: use hotplug script for EAP615-Wall MACs

[Stijn Tintel]

Using nvmem-cells to set the MAC address for a DBDC device results in
both PHY devices using the same MAC address. This in turn will result in
multiple BSSes using the same BSSID, which can cause various problems.

Use the hotplug script for the EAP615-Wall instead to avoid this.
