Tegra210: toggle ring oscillator across cluster idle

This patch toggles the ring oscillator state across cluster idle
as DFLL loses its state. We dont want garbage values being written
to the pmic when we enter cluster idle state, so enable "open loop"
when we enter CC6 and restore the state to "closed loop" on exit.
