due to the following patch, cpuidle: tegra: Check whether PMC is ready [ Upstream commit bdb1ffdad3b73e4d0538098fc02e2ea87a6b27cd ]

Check whether PMC is ready before proceeding with the cpuidle registration. This fixes racing with the PMC driver probe order, which results in a disabled deepest CC6 idling state if cpuidle driver is probed before the PMC.
