ethdev: add device fields from PCI layer

Browse Source 
The driver fields have been added the rte_eth_dev_data so that it is no
longer necessary access this data through the pci_dev pointer.

The following fields have been added to rte_eth_dev_data:

dev_flags, and macros for dev_flags.
kdrv
numa_node
drv_name

Add function rte_eth_copy_pci_info
