Merge branch 'pci/pwrctl'

Merge branch 'pci/pwrctl'

- Use of_platform_device_create() instead of of_platform_populate() to
  create pwrctl platform devices so we can control it based on the child
  nodes (Manivannan Sadhasivam)

- Create pwrctrl platform devices only if there's a relevant power supply
  property (Manivannan Sadhasivam)

- Add device link from the pwrctl supplier to the PCI dev to ensure pwrctl
  drivers are probed before the PCI dev driver; this avoids a race where
  pwrctl could change device power state while the PCI driver was active
  (Manivannan Sadhasivam)

- Find pwrctl device for removal with of_find_device_by_node() instead of
  searching all children of the parent (Manivannan Sadhasivam)

- Rename 'pwrctl' to 'pwrctrl' to use the same 'ctrl' suffix as 'bwctrl'
  and other PCI files to reduce confusion (Bjorn Helgaas)

* pci/pwrctl:
  PCI/pwrctrl: Rename pwrctrl functions and structures
  PCI/pwrctrl: Rename pwrctl files to pwrctrl
  PCI/pwrctl: Remove pwrctl device without iterating over all children of pwrctl parent
  PCI/pwrctl: Ensure that pwrctl drivers are probed before PCI client drivers
  PCI/pwrctl: Create pwrctl device only if at least one power supply is present
  PCI/pwrctl: Use of_platform_device_create() to create pwrctl devices
