We call pci_host_config_{read,write}_common() which perform PCI config
accesses. However they don't do all limit checking the way we expect
it to.
So let's introduce a small wrapper around them, making them behave the
way we would without touching generic code.
This patch is based on a patch by David Gibson which put this logic into
the generic code.

Currently on the pseries machine the SLOF firmware is used normally,
but we bypass it when -kernel is specified. Having these two
different boot paths can cause some confusion.
In particular at present we need to "probe" the (emulated) PCI bus and
produce device tree nodes for the PCI devices in qemu, for the -kernel
case. In the SLOF case, it takes the device tree from qemu adds some
stuff to it then passes it on to the kernel.
It's been decided that a better approach is to always boot through
SLOF, even when using -kernel. WIth this approach we can leave PCI
probing and device node creation to SLOF in all cases which removes a
bunch of code in qemu, and avoids iterating the PCI devices from the
machine specific init code which we're not supposed to do.
This patch changes qemu to always boot through SLOF, and not to create
PCI nodes. Simultaneously it updates the included version of SLOF
(submodule and binary image) to one which supports (and requires) the
new approach.
The new SLOF version also includes a number of unrelated enhancements:
support for booting from virtio-pci devices and e1000, greatly
improved FCode support and many bugfixes. It also makes SLOF ready to
be used even when specifying a kernel on the qemu command line.

The pseries machine expects a para-virtualized guest and so supplies RTAS
functions (via a hypercall) for performing PCI config space access.
Currently the implementation of these calls into
pci_default_{read,write}_config(). However this would be incorrect for
any PCI device which overrides the default config read/write functions.
AFAICT there's only one such device today, but we should still get it
right. In addition the pci_host_config_{read,write}_common() functions
which do correctly do this dispatch, perform bounds checking on the config
space address, lack of which currently leads to an exploitable bug.
This patch corrects the problem.

When accessing the device specific virtio config space, we memcpy
the data into a variable in QEMU. At that point we're basically
pulling host endianness into the game which is a really bad idea.
So instead, let's use the target specific load/store helpers for
memory pointers which fetch things in target endianness. The whole
array is already populated in target endianness anyways
(see virtio-blk).

The virtio config area in PIO space is a bit special. The initial
header is little endian but the rest (device specific) is guest
native endian.
The PIO accessors for PCI on machines that don't have native IO ports
assume that all PIO is little endian, which works fine for everything
except the above.
A complicated way to fix it would be to split the BAR into two memory
regions with different endianess settings, but this isn't practical
to do, besides, the PIO code doesn't honor region endianness anyway
(I have a patch for that too but it isn't necessary at this stage).
So I decided to go for the quick fix instead which consists of
reverting the swap in virtio-pci in selected places, hoping that when
we eventually do a "v2" of the virtio protocols, we sort that out once
and for all using a fixed endian setting for everything.

When running a 440 target, we currently get invalid irq_num values (-1)
which completely confuse the IRQ setting code.
This is most likely due to the missing qdev conversion.
While this shouldn't happen in the first place and should really rather
be fixed by converting the target, I dislike segfaults. So for now, let's
just print a warning and ignore invalid irq_num values.

To be able to support CPU reset, we need to put all register initialization

Based on the implementation from Hector Martin <hector@marcansoft.com>
Hectors's implementation completely sidestepped the qemu usb system and
used libusb directly for usb device pass through. So I've ripped out
the libusb bits (or left them in disabled, as reference for further
coding) and hooked up the qemu subsystem instead. That work is not
complete yet though, partly due to limitations of the qemu usb
subsystem. Nevertheless I think it is better to continue development
in-tree, especially as the qemu usb bits need a bunch of improvements
too for decent usb 3.0 support.
Current state:
- usb-storage emulation should work ok.
- Devices which need constant polling (HID emulation like usb-tablet)
are known to not work.
- ISO xfers are not implemented yet.
- superspeed ports are not implemented yet.
- usb pass-through is completely untested so far.
