  sparc/PCI: Correct 64-bit non-pref -> pref BAR resources (2026-01-07 14:22:32 -0600)

----------------------------------------------------------------

- Remove ASPM L0s support for MSM8996 SoC since we now enable L0s when
  advertised, and it caused random hangs on this device (Manivannan
  Sadhasivam)

- Fix meson-pcie to report that the link is up while in ASPM L0s or L1,
  since those are active states from the software point of view, and
  treating the link as down caused config access failures (Bjorn Helgaas)

- Fix up sparc DTS BAR descriptions that are above 4GB but not marked as
  prefetchable, which caused resource assignment and driver probe failures
  after we converted from the SPARC pcibios_enable_device() to the generic
  version (Ilpo Järvinen)
