This patch series is to prepare for enabling SR-IOV

and does not change any current functionality.
This patch which is currently in review is a dependency:

For a PCI device it's pci_dn can be retrieved from
pdev->dev.archdata.firmware_data, PCI_DN(devnode), or parent's list.
Thus, we should just use the existing function pci_get_pdn_by_devfn
to get the pci_dn.

This patch series is to prepare for enabling SR-IOV
on pseries. It separates the calls to be machine dependent
and does not change any current functionality.

powerpc/kernel: Split up pci_bus_add_device
pseries: Override pci_bus_match_virtfn_driver
powerpc/kernel: Separate
sriov_configure sysfs call
will not load the device driver as firmware will load
the device node when the VF device is assigned to the
logical partition. So we needed a way to overwrite the
way device driver matching is done for virtual functions
on powervm.

For Powervm SR-IOV (Pseries) enablement we dont want to match
the virtual function's device drivers since firmware
plans to load the device node in the device tree
dynamically when Novalink assigns the VF to a partition.

SR-IOV can now be enabled in PowerNV platforms and Pseries
platforms. Therefore, the appropriate calls were moved to
machine dependent code instead of definition at compile time.
