ARM: shmobile: rcar-gen2: Increase refcount for new reference
In rcar_gen2_regulator_quirk(), for_each_matching_node_and_match() will
automatically increase and decrease the refcount. However, we should
call of_node_get() for the new reference created in 'quirk->np'.
Besides, we also should call of_node_put() before the 'quirk' being
freed.
