Now I see... there is no difference. It seems that the whole idea of
opmode can be replaced with suspend modes and regulator modes.

I can't only find a way to set this from DTS. There are no bindings for
regulation_constraints->state_{disk,mem,standby}.

Should the driver set manually after obtaining init_data from DTS?
