Mattias Nissler de2c640f17 Add stub PCI device implementation. ... Introduce a very simple stub PCI device that can be added to the bus at a specified address with given PCI config parameters (vendor, device, etc.). This is useful for cases where we just require a device to be present during PCI enumeration. The case that motivates this is a vfio device passthrough configuration that passes only selected functions of a given device at the original addresses, but function 0 is not passed through. Absence of function 0 would be interpreted in enumeration as the entire device being absent (in accordance with the specification). Putting a stub device at function 0 fixes this. BUG=b:167947780 TEST=New unit test, boot minimal Linux image and verify enumerated PCI device.
