John Baldwin 25a57bd64b Add a loader tunable (hw.pci.enable_pcie_hp) to disable PCI-e HotPlug. 
Some systems and/or devices (such as riser cards) do not include a
non-compliant implementation of PCI-e HotPlug that can result in devices
not being attached (e.g. the HotPlug code might assume that a card is
being unplugged and will power the slot off and detach it).  This
tunable can be set to 0 to disable support for PCI-e HotPlug ignoring
the incorrect HotPlug state on these slots.
