[openib-general] moving IBM eHCA Device Driver to openib.org

[Shirley Ma]

Here is the Kconfig/Makefile patch I used to build ehca as a part of linux 
build.

I put out a initial set of files (as discussed) on openib.org svn. 
The Kconfig option will follow when I've verified that it really compiles 
as is in svn. 

The same set with makefiles and install scripts is available from 
sourceforge as ehca2_0033
