cpuidle: big.LITTLE: enable driver only on Peach-Pit/Pi Chromebooks
This driver always worked properly only on the Exynos 5420/5800 based Chromebooks (Peach-Pit/Pi), so change the required compatible string to the 'google,peach', to avoid enabling it on the other Exynos 542x/5800 boards, which hangs in such case. The main difference between Peach-Pit/Pi and other Exynos 542x/5800 boards is the firmware - Peach platform doesn't use secure firmware at all.
