ARM: 5952/1: ARM: MM: Add ARM_L1_CACHE_SHIFT_6 for handle inside each ARCH Kconfig
Add ARM_L1_CACHE_SHIFT_6 to arch/arm/Kconfig to allow CPUs with
L1 cache lines which are 64bytes to indicate this without having to
alter the arch/arm/mm/Kconfig entry each time.
Update the mm Kconfig so that ARM_L1_CACHE_SHIFT default value
uses this and change OMAP3 and S5PC1XX to select ARM_L1_CACHE_SHIFT_6.
