Two pmuio domains on ringneck are not defined: 1- PMUIO1: supplied by vcc_3v3 regulator(PMIC RK809) 2- PMUIO2: supplied by vcc_3v3 regulator(PMIC RK809) The reason why no functional effect was observed is because of that the above mentionned PMUIO domains were supplied by a regulator which is always on. So let's add their definition in the dtsi.
