This reverts commit cc8ed76938b5cf6a54ab3d60edabaf808dc960d1 ("soc: mediatek: SCPSYS: Fix double enabling of regulators") [1]. This patch fixes mt8173-evb failing boot issue. With commit [1], genpd state will not sync to real power domain state. So some resources such as clocks and regulators may stay in a wrong state. There is no regulator double enabling issue on mainline kernel, so we can refert commit [1] safely.
