Jonas Bonn 7b903e6c02 openrisc: provide dma_map_ops 
This switches OpenRISC over to fully using the generic dma-mapping
framework.  This was almost already the case as the architecture's
implementation was essentially a copy of the generic header.

This also brings this architecture in line with the recent changes
to dma_map_ops (adding attributes to ops->alloc).

Jonas Bonn 707b38a00b Add missing DMA ops 
For the initial architecture submission, not all of the DMA ops were
implemented.  This patch adds the *map_page and *map_sg variants of the
DMA mapping ops.

This patch is currently of interest mainly to some drivers that haven't
been submitted upstream yet.
