xrt is bringing in the subdir xrt/

Even after the likely move of xrt subdevices to other subsystems, there
will be about as many files in fpga/xrt/ as in fpga/

If both of you are fine with a mixed files and subdir organization, then
I'll drop this patchset.

If you want only files, then xrt needs to refactor, so let them know.
