[SPARC64]: Fix setting of variables in LDOM guest.
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. Signed-off-by: David S. Miller <davem@davemloft.net>
