Exynos5420 is big.Little Soc. It uses cpuidle-big-litle generic cpuidle driver.
Hence do not allow exynos cpuidle driver registration for Exynos5420.

Why not put this in exynos.c in exynos_dt_machine_init(), so
exynos_cpuidle_init() is called only if not running on Exynos5420?

That makes more sense.
I will update this

Thanks
