qemu: add capabilities bit for device x3130-upstream

This is the upstream part of a PCIe switch. It connects to a PCIe port
(but not PCI) on the upstream side, and can have up to 31
xio3130-downstream controllers (but no other types of devices)
connected to its downstream side.

This device will be used to implement the "pcie-switch-upstream-port"
model of pci controller.
