Nishanth Aravamudan 741d204cee powerpc/cell: Beat dma ops cleanup
direct_dma_ops is the default pci dma ops.

No need to call a function to get the pci dma ops, we know they are the
dma_direct_ops.

Grant Likely eca3930163 of: Merge of_platform_bus_type with platform_bus_type
of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code.  Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.

This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead.  A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.

After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.

Becky Bruce 738ef42e32 powerpc: Change archdata dma_data to a union
Sometimes this is used to hold a simple offset, and sometimes
it is used to hold a pointer.  This patch changes it to a union containing
void * and dma_addr_t.  get/set accessors are also provided, because it was
getting a bit ugly to get to the actual data.
