Changes in v5
Rebase to latest code.
Removed RTE_EXEC_ENV_BSDAPP from earlier changes.

Changes in v4
Move common functions in eal_pci.c to librte_eal/common/
eal_common_pci.c file.

Following functions are moved to eal_common_pci.c file.

void *pci_map_resource(void *requested_addr, const int vfio_fd,
      const char *devname, off_t offset, size_t size);
int pci_addr_comparison(struct rte_pci_addr *addr,
                        struct rte_pci_addr *addr2);
int rte_eal_pci_probe_one_driver(struct rte_pci_driver *dr,
                        struct rte_pci_device *dev);

Use RTE_EXEC_ENV_BSDAPP to differentiate minor differences in
common function.
Fix checkpatch warnings and errors.
