Fix some logic in PCIe HotPlug; display EI status

The interpretation of the Electromechanical Interlock Status was
inverted, so we disengaged the EI if a card was inserted.
Fix it to engage the EI if a card is inserted.

When displaying the slot capabilites/status with pciconf:

- We inverted the sense of the Power Controller Control bit,
  saying the power was off when it was really on (according to
  this bit).  Fix that.

- Display the status of the Electromechanical Interlock:
        EI(engaged)
        EI(disengaged)
