Attempt to make i915 rely more on the standard pci pm
code instead of hand rolling a bunch of
pci_save_state()+pci_set_power_state() stuff in the
driver.

Ville Syrjälä (6):
  PCI/PM: Respect pci_dev->skip_bus_pm in the .poweroff() path
  drm/i915/pm: Hoist pci_save_state()+pci_set_power_state() to the end
    of pm _late() hook
  drm/i915/pm: Simplify pm hook documentation
  drm/i915/pm: Move the hibernate+D3 quirk stuff into noirq() pm hooks
  drm/i915/pm: Do pci_restore_state() in switcheroo resume hook
  drm/i915/pm: Use pci_dev->skip_bus_pm for hibernate vs. D3 workaround
