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.

Rafael, Daniel,

would you mind if I took this into the Tegra tree? It's got a dependency
on the PMC driver, which usually goes via the Tegra tree already, and
there's nothing cpuidle-specific in here, it's all Tegra-specific
integration quirks.
