powerpc: expect all devices calling dma ops to have archdata set
Now that we set archdata for of_platform and platform devices via
platform_notify() we no longer need to special case having a NULL device
pointer or NULL archdata. It should be a driver error if this condition
shows up and the driver should be fixed.
