d5db9a4422 ARM: tegra: cpuidle: replace LP3 with ARM_CPUIDLE_WFI_STATE
The Tegra CPU idle LP3 state is doing ARM WFI only. So it's same with
the common ARM_CPUIDLE_WFI_STATE. Using it to replace LP3 now.

b4e395b2cb ARM: tegra: Remove flow controller programming
This particular code had no effect on WFI execution. It only
asserts/de-asserts signal to tegra "legacy" CPU idle stats
monitor, which we are no longer using (cpufreq is based on
kernel s/w idle stats instead).
