spapr-rtas: add ibm, (get|set)-system-parameter

Browse source 
This adds very basic handlers for ibm,get-system-parameter and
ibm,set-system-parameter RTAS calls.

The only parameter handled at the moment is
"platform-processor-diagnostics-run-mode" which is always disabled and
does not support changing. This is expected to make
"ppc64_cpu --run-mode=1" happy.
