Hmm. This changes the exit_latency/target_residency fields of the
cpuidle state definition from 10 to 1, and also replaces
tegra_idle_enter_lp3() with just a dsb/wfi as far as I can tell. What
are the implications of removing the irq/fiq_disable/enable and
ktim-related code? It might be worth explaining why this change is valid
in the commit description.
