spmi: hisi-spmi-controller: Drop duplicated OF node assignment in spmi_controller_probe()

spmi_controller_probe() assigns a parent device and an OF node to an
SPMI controller. However, the operations are not needed as they are
already assigned in spmi_controller_alloc(). Thus, remove the duplicated
assignments. An unnecessary OF node reference acquisition is also
dropped by this patch.
