Move the visorbus driver out of staging (drivers/staging/unisys/visorbus)
and to drivers/visorbus. Modify the configuration and makefiles so they
now reference the new location. The s-Par header file visorbus.h that is
referenced by all s-Par drivers, is being moved into include/linux.

The files are based off the latest revision in the staging-next tree: 

https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging.git

Changes from v1:
	-- Simplified to one single patch
	-- Combined include files into a single file
	-- Fixed the dependency flags that were in the wrong
	   location.
