Celleb always uses dma_direct_ops, and sets dma_direct_offset, so it
too should set dma_data to dma_direct_offset.
Currently there's no pci_dma_dev_setup() routine for Celleb so add one.

Store the direct_dma_offset in each device's dma_data in the case
where we're using the direct DMA ops.
We need to make sure we setup the ppc_md.pci_dma_dev_setup() callback
if we're using a non-zero offset.

PS3: Add repository polling loop to work around timing bug
On some firmware versions (e.g. 1.90), the storage device may not show up
in the repository immediately after receiving the notification message.
Add a small polling loop to make sure we don't miss it.

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.

Dynamically create the kset instead of declaring it statically. We also
rename power_subsys to power_kset to catch all users of the variable and
we properly export it so that people don't have to guess that it really
is present in the system.

is disabled? Oh well, stupid big boxes ignoring config options...

We don't need a "default" ktype for a kset. We should set this
explicitly every time for each kset. This change is needed so that we
can make ksets dynamic, and cleans up one of the odd, undocumented
assumption that the kset/kobject/ktype model has.
This patch is based on a lot of help from Kay Sievers.

This patch adds support for 'mpc5200-simple-platform' compatible
boards which do not need a platform specific setup. Such boards
are supported assuming the following:
- GPIO pins are configured by the firmware,
- CDM configuration (clocking) is setup correctly by firmware,
- if the 'fsl,has-wdt' property is present in one of the
gpt nodes, then it is safe to use such gpt to reset the board,
- PCI is supported if enabled in the kernel configuration
and if there is a PCI bus node defined in the device tree.

xlate_iomm_address() really wants the ds_addr to pass to the HV, so store
that value (instead of the BAR number) when we allocate the device bars.
This is not a fast path, so we can look up the device_node property
there instead of using the bussubno field of the pci_dn.
The other user of iseries_ds_addr() was already scanning the device tree,
so looking up a property will not slow it down any more.

looking for specific nodes, except that they take of_device_id
