[dpdk-dev] [PATCH] 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.

Cc: Pablo de Lara <pablo.de.lara.guarch@intel.com>

There is no deprecation notice sent for this update but in this release
ethdev info already updated and ABI already broken, it can be good
opportunity for this update.
