fpga: add subsystem vendor & device fields to PCIDevice

[jstamel]

Adds subsystem vendor and device information to PCIDevice struct.

Useful for distinguishing different FPGA boards driven by the DFL driver, where vendor and device ID are the same (DFL PCI IDs).

Hi @jstamel and thanks for the PR. @bart0sh and/or @kad would you mind taking a look? From my point of view, the change is fine.

@jstamel apologies for the silence

what is the gap you're observing with the plugin? AFAUI, we are not limiting the device selection based on these. See #621 and #625.

@mythi No problem and thanks for your comment.

I don't observe any gap regarding the device plugin functionality.
However, having that in place, provides more info about the underlying PCIDevice.

In my case, I need this because I work on a project for fetching FME sensors and I use your FPGA package as a library for instantiating available FMEs. What is more, my project follows the OPAE way of enumerating FPGA sensors for different FPGA HW types, that can be identified through the subsystem vendor and subsystem device IDs.

@jstamel makes sense, thanks for the quick response. I'll get this merged asap (CI needs fixing first)
