The a7 area was set up as an alias of itself, rather than the p4 area. This
sent the memory core into infinite recursion.
Fix by aliasing the a7 area to the p4 area.

This is now done sloppily, via get_system_memory(). Eventually callers
will be converted to stop using that.

This patch converts the ISA MMIO bridge code to always use little endian mmio.
All bswap code that existed was only there to convert from native cpu
endianness to little endian ISA devices.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

Since commit 8da3ff1809 ("MMIO callback
interface changes"), the addresses passed to the I/O functions are an
offset to the start of the area. As a consequence, there is no need to
correct the address using the value of IOBR. This make possible the use
of the default MMIO functions. Moreover the addresses are now remaped
when the value if IOBR change.
The memory area corresponds to the devices behing the PCI bus, it should
not be mapped by the PCI controller. Remove the corresponding code.

Now pci host stuff has been moved from pci.[hc] to pci_host.[hc]
so the declaration of pci_data_{read, write}() should be in
pci_host.h
This patch moves them from pci.h to pci_host.h for consistency.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b72.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Implement and use a common device bus state. The main side-effect is
that creating a bus and attaching it to a parent device are no longer
separate operations. For legacy code we allow a NULL parent, but that
should go away eventually.
Also tweak creation code to veriry theat a device in on the right bus.

This patch adds and uses #defines for the remaining hardcoded PCI
device IDs. It also moves definitions taken from linux/pci_ids.h
into a separate header (hw/pci_ids.h), removes the 'RTL' from
PCI_DEVICE_ID_REALTEK_RTL8029, and renames PCI_DEVICE_ID_FSL_E500
to PCI_DEVICE_ID_MPC8533E to match Linux's definition.
Changes in v2:
* Don't use C99-style comments
* Move definitions from linux/pci_ids.h into a separate header
* Rename PCI_DEVICE_ID_FSL_E500 to PCI_DEVICE_ID_MPC8533E
