hw/cxl: Add a switch mailbox CCI function CXL switch CCIs were added in CXL r3.0. They are a PCI function, identified by class code that provides a CXL mailbox (identical to that previously defined for CXL type 3 memory devices) over which various FM-API commands may be used. Whilst the intent of this feature is enable switch control from a BMC attached to a switch upstream port, it is also useful to allow emulation of this feature on the upstream port connected to a host using the CXL devices as this greatly simplifies testing.

pci/pci_expander_bridge: For CXL HB delay the HB register memory region setup. As the CXLState will no long be accessible via MachineState at time of PXB_CXL realization, come back later from the machine specific code to fill in the missing memory region setup. Only at this stage is it possible to check if cxl=on, so that check is moved to this later point. Note that for multiple host bridges, the allocation order of the register spaces is changed. This will be reflected in ACPI CEDT. Stubs are added to handle case of CONFIG_PXB=n for machines that call these functions. The bus walking logic is common to all machines so add a utility function + stub to cxl-host*.
