[PATCH] PCI Hotplug: rpaphp: Purify hotplug

Browse Source 
Currently rpaphp registers the following bus types as hotplug slots:
1) Actual PCI Hotplug slots
2) Embedded/Internal PCI slots
3) PCI Host Bridges

The second and third bus types are not actually direct parents of
removable adapters.  As such, the rpaphp has special case code to fake
results for attributes like power, adapter status, etc.  This patch
removes types 2 and 3 from the rpaphp module.

This patch also changes the DLPAR module so that slots can be
DLPAR-added/removed without having been designated as hotplug-capable.
