Remove struct eth_driver

I rebased the following work of Jan:

This series is removing the PCI specific struct eth_driver from rte_ether. The PCI drivers are changed to use the newly introduced header-only helpers instead. Although the virtual drivers did not make use of the ethdev's driver field they are converted to use the VDEV specific allocation helpers. The motivation for this change is to properly embed a reference to the generic rte_device in the ethdev.

The series is based on:

* http://dpdk.org/dev/patchwork/patch/20416/
* http://dpdk.org/dev/patchwork/patch/20417/
* The "Rework vdev probing to use rte_bus infrastructure" series
* http://dpdk.org/dev/patchwork/patch/21058/

Changes in v2:
* Removed the patch "net/vmxnet3: use library function for DMA zone reserve" It is essentially duplicating the following commit:
04df93d1edac ("net/vmxnet3: fix queue size changes")
* Fixed header includes for mlx4 and mlx5 PMD
* Followed the changes of the series for new PMDs (AVP, liquidio)
* Made KNI use the new API
* Made PCAP use the new API
* Fixed undefined behavior on vdev driver arg parsing
* Fixed virtual_pmd for unit test
