Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

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.
