Add common inbound memory mapping/unmapping interface. This allows to make
local memory space accessible from the RapidIO side using hardware mapping
capabilities of RapidIO bridging devices. The new interface is intended to
enable data transfers between RapidIO devices in combination with DMA engine
support.

Adds DMA Engine framework support into RapidIO subsystem.
Uses DMA Engine DMA_SLAVE interface to generate data transfers to/from
remote RapidIO target devices.
Introduces RapidIO-specific wrapper for prep_slave_sg() interface with an
extra parameter to pass target specific information.
Uses scatterlist to describe local data buffer. Address flat data buffer
on a remote side.

The <linux/device.h> header includes a lot of stuff, and
it in turn gets a lot of use just for the basic "struct device"
which appears so often.
Clean up the users as follows:
1) For those headers only needing "struct device" as a pointer
in fcn args, replace the include with exactly that.
2) For headers not really using anything from device.h, simply
delete the include altogether.
3) For headers relying on getting device.h implicitly before
being included themselves, now explicitly include device.h
4) For files in which doing #1 or #2 uncovers an implicit
dependency on some other header, fix by explicitly adding
the required header(s).
Any C files that were implicitly relying on device.h to be
present have already been dealt with in advance.
Total removals from #1 and #2: 51. Total additions coming
from #3: 9. Total other implicit dependencies from #4: 7.
As of 3.3-rc1, there were 110, so a net removal of 42 gives
about a 38% reduction in device.h presence in include/*

This set of patches eliminates RapidIO dependency on PowerPC architecture
and makes it available to other architectures (x86 and MIPS). It also
enables support of new platform independent RapidIO controllers such as
PCI-to-SRIO and PCI Express-to-SRIO.
This patch:
Extend number of mport callback functions to eliminate direct linking of
architecture specific mport operations.

Change code to use one storage location common for switches and endpoints.
This eliminates unnecessary device type checks during basic access
operations. Logic that assigns destid to RIO devices stays unchanged - as
before, switches use an associated destid because they do not have their
own.
