Upstream ATF has all the power domain init on.
Downstream ATF not have all the power domain init on.
Upstream/downstream U-Boot use SIP to trap to ATF to power on domain.
Downstream Linux use SIP for power domain
Upstream Linux not have power domain support. We are thinking SCMI or
others for upstream Linux.
