Markus Armbruster 65c326ce51 include/hw/cxl: Move typedef PXBDev to cxl.h, and put it to use
hw/cxl/cxl.h uses the PXBDev structure tag instead of the typedef
name.  The typedef name is defined in hw/pci/pci_bridge.h.  Its
inclusion was dropped in the previous commit to break an inclusion
loop.

Move the typedef to hw/cxl/cxl.h, and use it there.  Delete an extra
typedef in hw/pci-bridge/pci_expander_bridge.c.
