FUJITA Tomonori 349004294c dma-mapping: sparc: unify 32bit and 64bit dma_set_mask 
This patchset transforms the PCI DMA API into the generic device model.
It's one of the reasons why we introduced the generic DMA API long ago;
driver writers are always able to use the generic DMA API with any bus
instead of using bus specific DMA APIs such as pci_map_single,
sbus_map_single, etc (only two bus specific APIs exist now; pci and ssb).

Some of the PCI DMA API are already implented on the top of the generic
DMA API (include/asm-generic/pci-dma-compat.h).  But there are some
exceptions.  This patchset finishes the transformation.

This patch:

sparc has two dma_set_mask implementations for 32bit and 64bit.  They are
same except for the error returned value.  We can safely unify them since
the error returned value doesn't matter as long as it is negative (as
DMA-API.txt describes).

This patch also changes dma_set_mask not to call
pci_set_dma_mask. Instead, dma_set_mask does the same thing that
pci_set_dma_mask does. This change enables ut to change
pci_set_dma_mask to call dma_set_mask; we can implement
pci_set_dma_mask as pci-dma-compat.h does.
