  PCI/ASPM: Enable only L0s and L1 for devicetree platforms (2025-10-23 20:08:14 -0500)

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

- Add DWC custom pci_ops for the root bus instead of overwriting the DBI
  base address, which broke drivers that rely on the DBI address for iATU
  programming; fixes an FU740 probe regression (Krishna Chaitanya Chundru)

- Revert qcom ECAM enablement, which is rendered unnecessary by the DWC
  custom pci_ops (Krishna Chaitanya Chundru)

- Fix longstanding MIPS Malta resource registration issues to avoid
  exposing them when the next commit fixes the boot failure (Maciej W.
  Rozycki)

- Use pcibios_align_resource() on MIPS Malta to fix boot failure caused by
  using the generic pci_enable_resources() (Ilpo Järvinen)

- Enable only ASPM L0s and L1, not L1 PM Substates, for devicetree
  platforms because we lack information required to configure L1 Substates;
  fixes regressions on powerpc and rockchip.  A qcom regression (L1
  Substates no longer enabled) remains and will be addressed next (Bjorn
  Helgaas)
