[dpdk-dev] [PATCH v6] ethdev: replace bus specific struct with generic dev

[Ferruh Yigit <ferruh.yigit@intel.com>]

Public struct rte_eth_dev_info has a "struct rte_pci_device" field in it
although it is common for all ethdev in all buses.

Replacing pci specific struct with generic device struct and updating
places that are using pci device in a way to get this information from
generic device.

v2:
- prevent possible crash while getting bus (Pablo)
- Remove unnecessary __rte_unused
- Some PMD info_dev->device was assigned to NULL, fixed them

v3:
- rebased on latest next-net

v4:
- Move dev_info->device assignment to ethdev layer

v5:
- Document API change in related section in release notes

v6:
- Rebase on latest next-net, ip_pipeline updated
- Update axgbe too
