Merge branch 'pci/resource'

- Add resource_set_size() to set resource size when start has already been
  set (Ilpo Järvinen)

- Add resource_set_range() helper to set both resource start and size (Ilpo
  Järvinen)

- Use IS_ALIGNED() and resource_size() in quirk_s3_64M() instead of
  open-coding them (Ilpo Järvinen)

- Add ALIGN_DOWN_IF_NONZERO() to avoid code duplication when distributing
  resources across devices (Ilpo Järvinen)

- Improve pdev_sort_resources() warning message to be more specific (Ilpo
  Järvinen)

* pci/resource:
  PCI: Improve pdev_sort_resources() warning message
  PCI: Add ALIGN_DOWN_IF_NONZERO() helper
  PCI: Use align and resource helpers, and SZ_* in quirk_s3_64M()
  PCI: Use resource_set_{range,size}() helpers
  resource: Add resource set range and size helpers
