[PATCH] via-velocity: Remove private device list

[Ben Hutchings <ben@decadent.org.uk>]

[-- Attachment #1: Type: text/plain, Size: 3354 bytes --]

via-velocity maintains a list of its devices in order to determine
whether a netdev notification applies to one of them.  That can be
determined simply by checking the netdev_ops pointer, so the list can
be removed.

Compile-tested only.
