[PATCH] hw/arm/cubieboard: make sure SOC object isn't leaked

[Igor Mammedov <imammedo@redhat.com>]

SOC object returned by object_new() is leaked in current code.
Set SOC parent explicitly to board and then unref to SOC object
to make sure that refererence returned by object_new() is taken
care of.

The SOC object will be kept alive by its parent (machine) and
will be automatically freed when MachineState is destroyed.
