[PATCH] bus/vdev: automatically add eth alias for net drivers

[Bruce Richardson <bruce.richardson@intel.com>]

For historical reasons, a number of net vdev drivers also add a driver
alias using the "eth_" prefix. Since this is done on a per-driver basis,
the use of the alias in inconsistent and is spread across multiple
files. We can remove the per-driver aliases by just adding the alias
automatically at the vdev bus level.
