Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile
board, since we weren't swizzling IRQs based on the slot number.
Since this change would otherwise break any uses of PCI on Linux kernels
which have an equivalent bug (since they have effectively only been
tested against QEMU, not real hardware), we implement a mechanism
for automatically detecting those broken kernels and switching back
to the old mapping. This works by looking at the values the kernel
writes to the PCI_INTERRUPT_LINE register in the config space, which
is effectively the interrupt number the kernel expects the device
to be using.

Update the Versatile PCI controller to use a realize function rather
than SysBusDevice::init. To reflect the fact that the 'realview_pci'
class is taking most of its implementation from 'versatile_pci' (and
to make the QOM casts work) we make 'realview_pci' a subclass of
'versatile_pci'.

Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments.
This change removes the only currently implemented difference
between the realview-pci and versatile-pci models; however there
are other differences in not-yet-implemented functionality, so we
retain the distinction between the two device types.

Configure to use the DTC submodule to build libfdt when no system libfdt

DTC has no out-of-tree build capability, so the configure will symlink
the Makefile and scripts directory in the out of tree build directory
and pass in all the needed DTC arguments to make out of tree build happen.
Ideally we fix the DTC make to support out of tree, but did it this way to
avoid commits to DTC.

This test compares all of the default register values against the
spec. It turns out we deviate in quite a few places. These
places are really only visible to the BIOS though which is why
this hasn't created any problems.
The deviation actually happens in the core PCI layer so I suspect
it's not a simple fix if we really care to fix it. For now, just
