The patches intend to utilize the PCI slot reset capability exposed from
the skiboot firmware, which requires corresponding changes as follows:
Changelog
=========
v2 -> v3
* Rebased to Richard's SRIOV patchset.
* Removed hotplug part, which needs rework.
v1 -> v2
* Keep opal_pci_reinit(). In case the slot is resetted by kernel,
instead of skiboot, this API should be called to restore states
for those affected devices.
* Reworked slot ID scheme so that old/new kernel can work with
skiboot with or without unified PCI slot management support.
* Code cleanup here and there.
* Separate powernv-php driver to support PCI hotplug for
PowerNV platform.
* Check if the OPAL API supported by firmware before calling
into it, which is necessary for back-compability.
* Separate patch for factoring pnv_pci_poll().
