[PATCH] PCI: rpaphp: remove init error condition 

The init function for the RPA PCI Hotplug driver returns -ENODEV in the
case that no hotplug-capable slots are detected in the system.  This is
bad, since hot-capable slots can be added after boot to a purely virtual
POWER partition.  This is also bad because DLPAR I/O operations depend
on the rpaphp module.

Change the rpaphp init module to return success for the case of
partitions that own no hotplug-capable slots at boot.  Such slots can be
dynamically added after boot.
