This reworks RTAS code to use predefined macros vs. numbers and
adds handlers for ibm,get-system-parameter and ibm,set-system-parameter.

  spapr-rtas: replace constants with macros
  spapr-rtas: add ibm,(get|set)-system-parameter

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.

Changes:
v3:
* reworked all return codes (in a separate patch)

v2:
* addressed comments from Alex Graf

Sorry, saw that one too late. What is a papameter? Is it related to the pope? :)
