[PATCH] ppc64: update info about available iseries_veth interfaces

From: Olaf Hering <olh@suse.de>

/proc/iSeries/config contains now the number of configured virtual ethernet
adapters.  AVAILABLE_VETH should only indicate if there is at least one
interface available, iseries_veth must be loaded in this case.

Printing the entire map will give installers some hints about what
interface numbers will appear and how the MAC address may look like.
