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.

hw/pci-bridge/cxl_upstream: Move defintion of device to header.

To avoid repetition of switch upstream port specific data in the
CXLDeviceState structure it will be necessary to access the switch USP
specific data from mailbox callbacks. Hence move it to cxl_device.h so it
is no longer an opaque structure.
