PCI: Remove untested Electromechanical Interlock (EMI) support in pciehp.
The EMI support in pciehp is obviously broken. It is implemented using struct hotplug_slot_attribute, but sysfs_ops for pci_slot_ktype is NOT for struct hotplug_slot_attribute, but for struct pci_slot_attribute. This bug had been there for a long time, maybe it was introduced when PCI slot framework was introduced. The reason why this bug didn't cause any problem is maybe the EMI support is not tested at all because of lack of test environment. As described above, the EMI support in pciehp seems not to be tested at all. So this patch removes EMI support from pciehp, instead of fixing the bug.
