In menu_select function we check for correction factor every time.
If it is zero we are initializing to unity. Hence move it to init function
and initialise by unity, hence avoid repeated comparisons.

Chander Kashyap (4):
cpuidle: config: Add SOC_EXYNOS5420 entry to select
cpuidle-big
Exynos5420 is a big-little SoC from Samsung. It has 4 A15 and 4 A7 cores.
In order to use generic cpuidle-big-little driver, this patch adds Exynos5420
specific check to initialize generic cpuidle driver.

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

In order to support cpuidle through mcpm, suspend and powered-up
callbacks are required in mcpm platform code.
Hence populate the same callbacks.

Replace irq_domain_add_simple with "irq_domain_add_linear" in order to use
linear irq domain, and to remove hardcoded irq_base_value.
