regulator: qcom_spmi: Do NULL check for lvs
Low-voltage switches (lvs) don't have set_points since the voltage ranges of the output are really controlled by the inputs. This is a problem for the newly added linear range support in the probe(), as that will cause a null pointer dereference error on older platforms like msm8974 which happen to need to control some of the implemented lvs. Fix this by adding the appropriate null check.
