kconfig: Add PCIe devices to s390x machines

It is useful to extend the number of available PCIe devices to KVM guests
for passthrough scenarios and also to expose these models to a different
(big endian) architecture. Introduce a new config PCIE_DEVICES to select
models, Intel Ethernet adapters and one USB controller. These devices all
support MSI-X which is a requirement on s390x as legacy INTx are not
supported.

kconfig: add CONFIG_MSI_NONBROKEN

Not all interrupt controllers have a working implementation of
message-signalled interrupts; in some cases, the guest may expect
MSI to work but it won't due to the buggy or lacking emulation.

In QEMU this is represented by the "msi_nonbroken" variable. This
patch adds a new configuration symbol enabled whenever the binary
contains an interrupt controller that will set "msi_nonbroken". We
can then use it to remove devices that cannot be possibly added
to the machine, because they require MSI.

build: convert pci.mak to Kconfig

Instead of including the same list of devices for each target,
set CONFIG_PCI to true, and make the devices default to present
whenever PCI is available. However, s390x does not want all the
PCI devices, so there is a separate symbol to enable them.

Done mostly with the following script:

while read i; do
i=${i%=y}; i=${i#CONFIG_}
sed -i -e'/^config '$i'$/!b' -en \
-e'a\' -e' default y if PCI_DEVICES\' -e' depends on PCI' \
`grep -lw $i hw/*/Kconfig`
done < default-configs/pci.mak

followed by replacing a few "depends on" clauses with "select"
whenever the symbol is not really related to PCI.

kconfig: introduce kconfig files

The Kconfig files were generated mostly with this script:

set fnord `git grep -lw $i -- 'hw/*/Makefile.objs' `
shift

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.
