ixp4xx: Support single zcom_npe_esa hw address

Browse Source 
Some ixp4xx platforms with a proper RedBoot config do not
contain the per-ethernet interface npe_eth0_esa, but rather
a single entry named zcom_npe_esa.

Let's use this if fconfig can't find the primary key.
This is needed on the Netgear WG302 v1.
