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).

There are numerous broken references to Documentation files (in other
Documentation files, in comments, etc.). These broken references are
caused by typo's in the references, and by renames or removals of the
Documentation files. Some broken references are simply odd.
Fix these broken references, sometimes by dropping the irrelevant text
they were part of.

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.

Simple DMA implementation. Allows for allocation of coherent memory
(simply uncached) for DMA operations.
