Tegra194: reset power state info for CPUs
We set deepest power state when offlining a core but that may not be requested by non-secure sw which controls idle states. It will re-init this info from non-secure software when the core come online. This patch resets the power state in the non-secure world context to allow it to start with a clean slate.
