[Skiboot] [RFC PATCH 0/3] Changes to restoring buses after reset

[Jordan Niethe]

These are RFC patches for reworking how buses are restored after
performing a fundamental reset.  The goals for this:
    1: Get rid delays in skiboot to stop holding up
       OPAL_PCI_RESET calls
    2: Ensure slots with power controllers restore their state

Jordan Niethe (3):
  core/pci: Add functions for iterating pci devices
  hw/phb4: Restore bus numbers with a state machine
  hw/phb4: Restore slot power controller state
