Date: Thu, 22 Oct 2015 19:57:50 +0800

Support PCI-e device hot-add multi-function via device_add, just ensure
add the function 0 is added last. While allow user to roll back in the
middle via device_del, in case user cancle the operation.

changelog v4:
1. take ari into account, add api: pci_is_function_0()
2. reorder the patch
3. other minor fix according to the v3 comment

changelog v3:
1. Flag device as unexposed when func 0 doesn`t exist, via return 0xFF
   in case of gratuitous pci bus scan.
2. Since device is unexposed to guest, can remove function individually,
   without interaction with the guest.

Cao jin (2):
  remove function during multi-function hot-add
  enable multi-function hot-add
