[POWERPC] PS3: Use the HVs storage device notification mechanism properly
The PS3 hypervisor has a storage device notification mechanism to wait
until a storage device is ready. Unfortunately the storage device
probing code used this mechanism in an incorrect way, needing a
polling loop and handling of devices that are not yet ready.
This change corrects this by:
- First waiting for the reception of an asynchronous notification
that a new storage device became ready,
- Then looking up the storage device in the device repository.
On shutdown, the storage probe thread is stopped and the storage
notification device is closed using a reboot notifier.
