rockchip: fix the scu idle for rk3399
As rk3399 reported the d8/octane scores drop 10% with cpu idle. The root cause is thc cpu cluster enter the slow mode. We don't need switch the clock to 24MHz if cpu cluster enter the retention mode. In order to improve performance, it just needs for cluster enter powering off mode. Also, we shouldn't do anything for hlvl if the system is off. Change-Id: I2a02962a01343abd0cba47ed63192c1cdf88b119
