PCI: pci-bridge-emul: Add support for PCI Bridge Subsystem Vendor ID capability
This is read-only capability in PCI config space. Put it between base PCI
capability and base PCI Express capability.
Driver just have to specify subsystem_vendor_id and subsystem_id fields in
emulated bridge structure and pci-bridge-emul takes care of correctly
compose PCI Bridge Subsystem Vendor ID capability.
