Unlike the decoder enumeration for "root decoders" described by platform firmware, standard decoders can be enumerated from the component registers space once the base address has been identified (via PCI, ACPI, or another mechanism). Add common infrastructure for HDM (Host-managed-Device-Memory) Decoder enumeration and share it between host-bridge, upstream switch port, and cxl_test defined decoders. The locking model for switch level decoders is to hold the port lock over the enumeration. This facilitates moving the dport and decoder enumeration to a 'port' driver. For now, the only enumerator of decoder resources is the cxl_acpi root driver.
