[PATCH v2] kconfig: Add PCIe devices to s390x machines

[Cédric Le Goater]

It is useful to extend the number of available PCI devices to KVM guests
for passthrough scenarios and also to expose these models to a different
(big endian) architecture. Include models for Intel Ethernet adapters
and one USB controller, which all support MSI-X. Devices only supporting
INTx won't work on s390x.

 Tested under KVM as a machine device, under KVM nested as a passthrough
 device
