Dan Williams	98d2d3a264	cxl/core: Generalize dport enumeration in the core ... The core houses infrastructure for decoder resources. A CXL port's dports are more closely related to decoder infrastructure than topology enumeration. Implement generic PCI based dport enumeration in the core, i.e. arrange for existing root port enumeration from cxl_acpi to share code with switch port enumeration which just amounts to a small difference in a pci_walk_bus() invocation once the appropriate 'struct pci_bus' has been retrieved. Set the convention that decoder objects are registered after all dports are enumerated. This enables userspace to know when the CXL core is finished establishing 'dportX' links underneath the 'portX' object.

Dan Williams	af9cae9fac	cxl/pci: Rename pci.h to cxlpci.h ... Similar to the mem.h rename, if the core wants to reuse definitions from drivers/cxl/pci.h it is unable to use <pci.h> as that collides with archs that have an arch/$arch/include/asm/pci.h, like MIPS.
