rockchip: Disable rdist before pwr_dm_suspend is called

This disables the redistributor before either of the pwr_dm_suspend
functions are called. This is because the rdist save code in the
rk3399 rockchip_soc_sys_pwr_dm_suspend function requires that each
redistributor be disabled before saving state.
