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.

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.

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*.

This converts existing DECLARE_INSTANCE_CHECKER usage to
OBJECT_DECLARE_SIMPLE_TYPE when possible.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.
This commit was created with scripts/clean-includes, with the change
to target/s390x/gen-features.c manually reverted, and blank lines
around deletions collapsed.

Here we rename PBMPCIBridge to SimbaPCIBridge and the QOM type from
TYPE_PBM_PCI_BRIDGE to TYPE_SIMBA_PCI_BRIDGE in improve the clarity
of the device name.
Also touch up the relevant spots in apb.c and various other function
names as appropriate.

Move the QOM type and macros into a new include/hw/pci-bridge/simba.h
file, and add a new CONFIG_SIMBA Makefile.objs variable which is enabled
for sparc64-softmmu builds only.
