ntb: intel: fix port config status offset for SPR
commit d5081bf upstream. The field offset for port configuration status on SPR has been changed to bit 14 from ICX where it resides at bit 12. By chance link status detection continued to work on SPR. This is due to bit 12 being a configuration bit which is in sync with the status bit. Fix this by checking for a SPR device and checking correct status bit.
