spapr: Fix implementation of Open Firmware client interface

Browse source 
This addresses the comments from v22.

The functional changes are (the VOF ones need retesting with Pegasos2):

(VOF) setprop will start failing if the machine class callback
did not handle it;
(VOF) unit addresses are lowered in path_offset();
(SPAPR) /chosen/bootargs is initialized from kernel_cmdline if
the client did not change it.
