[SPARC64]: Fix setting of variables in LDOM guest.

Browse Source 
There is a special domain services capability for setting
variables in the OBP options node.  Guests don't have permanent
store for the OBP variables like a normal system, so they are
instead maintained in the LDOM control node or in the SC.
