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.
