This adds a new device that we can use for testing PCI PIO and MMIO, with and
 without ioeventfd in different configurations.  FAST_MMIO will be added if/when
 kvm supports it.  Also included are minor cleanups in kvm APIs that it needs.

a540f158db configure/Make: Build libfdt from submodule DTC
Configure to use the DTC submodule to build libfdt when no system libfdt
is found. Prompt to install the DTC submodule if --enable-fdt is set but
no DTC can be found.

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.

9bda413c96 i440fx-test: add test to compare default register values
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
disable the affected checks.
