mb/hp/z220_series: Improve the port for z220_sff_workstation

- Move configs for PCIe ports not present on z220_sff_workstation
  from the devicetree.cb of base board to the overridetree.cb of
  z220_cmt_workstation.

- Add a note for ME/AMT Flash Override jumper, for it is hard to
  flash from OEM firmware either internally or externally without
  closing this jumper.

- Add a side note for similar HP Compaq Elite 8300 SFF.
