regulator: Fix default constraints for fixed voltage regulators
Default voltage constraints were being provided for fixed voltage regulator where board constraints were not provided but these constraints used INT_MIN as the default minimum voltage which is not a valid value since it is less than zero. Use 1uV instead. Also set the default values we set in the constraints themselves since otherwise the max_uV constraint we determine will not be stored in the actual constraint strucutre and will therefore not be used.
