[v2,0/7] Removal of PCI bus ABIs

  As announced in the deprecation notice, most ABIs in PCI bus will be removed.

As there exist some applications that want to access PCI memory resource,
two new APIs are defined in Patch 1 and corresponding changes are applied
to testpmd in Patch 2.

Patch 3-4 clean up the unnecessary usage of PCI bus header in examples.

Patch 5-6 clean up the unused PCI related structure in kni library and related
tests and examples.

Patch 7 finally removes most of ABIs in PCI bus.

---
v2: 
 - Add check on call of port_id_pci_reg_write (Xiaoyun)
 - Combine two clean-up patches in test and example, and backport (David)

Chenbo Xia (7):
  bus/pci: add new memory resource access APIs
  app/testpmd: use PCI memory resource access APIs
  examples/ethtool: use PCI library API to get PCI address
  examples/kni: remove unused PCI bus header
  kni: remove unused PCI info from test and example
  kni: replace unused variable definition with reserved bytes
  bus/pci: remove ABIs in PCI bus
