    pci: Adapt PME capability queries to stable/14
    
    Add explicit D3hot and D3cold names and the bounds needed by
    pci_has_pme(), while retaining PCI_POWERSTATE_D3 == 3.  D3cold is a
    capability-query state here, not a newly supported power transition.
    This avoids importing the ACPI D3cold changes for the PME and igc
    Wake-on-LAN backports.
    
    Use pci_has_pm() to check capability presence instead of pp_location,
    which is not present in stable/14.  Keep the PCI configuration structure
    layout unchanged.
    
    Fixes: d831cb2ad3d8 ("pci: Expose PME support by power state")
    Fixes: 443dc80b712c ("igc: Correct Wake-on-LAN filter programming")
