hw/vfio: Move the IGD quirk code to a separate file

The IGD quirk code defines a separate device, the so-called
"vfio-pci-igd-lpc-bridge" which shows up as a user-creatable
device in all QEMU binaries that include the vfio code. This
is a little bit unfortunate for two reasons: First, this device
is completely useless in binaries like qemu-system-s390x.
Second we also would like to disable it in downstream RHEL
which currently requires some extra patches there since the
device does not have a proper Kconfig-style switch yet.

So it would be good if the device could be disabled more easily,
thus let's move the code to a separate file instead and introduce
a proper Kconfig switch for it which gets only enabled by default
if we also have CONFIG_PC_PCI enabled.

vfio-pci: enable by default

CONFIG_VFIO_PCI was not "default y" - and once you do that, it is also
important to disable it if PCI is not there.

vfio: express vfio dependencies with Kconfig

build: switch to Kconfig

The make_device_config.sh script is replaced by minikconf, which
is modified to support the same command line as its predecessor.

The roots of the parsing are default-configs/*.mak, Kconfig.host and
hw/Kconfig. One difference with make_device_config.sh is that all symbols
have to be defined in a Kconfig file, including those coming from the
configure script. This is the reason for the Kconfig.host file introduced
in the previous patch. Whenever a file in default-configs/*.mak used
$(...) to refer to a config-host.mak symbol, this is replaced by a
Kconfig dependency; this part must be done already in this patch
for bisectability.

kconfig: introduce kconfig files

The Kconfig files were generated mostly with this script:

sed -i '$d' hw/*/Kconfig
for i in hw/*; do
if test -d $i && ! test -f $i/Kconfig; then
touch $i/Kconfig
git add $i/Kconfig
fi
done

Whenever a symbol is referenced from multiple subdirectories, the
script prints the list of directories that reference the symbol.
These symbols have to be added manually to the Kconfig files.

Kconfig.host and hw/Kconfig were created manually.
