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.
