[PATCH 13/16] sparc: use generic dma_set_mask

[Christoph Hellwig <hch@lst.de>]

Sparc already uses the same code as the generic code for the PCI
implementation but just fails the call sbus.  This moves to the
generic implemenation which eventually return -EIO due to the NULL
dma_mask pointer in the device.
