Change PMT class code to pass a discovery index rather than a direct struct
resource when creating entries. This allows the class to identify the
discovery source generically without assuming PCI BAR resources. For PCI
devices, the index still resolves to a resource in the intel_vsec_device.
Other discovery sources, such as ACPI, can use the same index without
needing a struct resource.
