[PATCH] ARM: MM: Add ARM_L1_CACHE_SHIFT_BY6 for handle inside each ARCH Kconfig

[Kukjin Kim]

This patch adds ARM_L1_CACHE_SHIFT_BY6 into arch/arm/Kconfig. Basically,
ARM L1 cache line size is 32Bytes. Therefore, whenever new ARCH which
has 64Bytes L1 cache line size is added, have to set ARM_L1_CACHE_SHIFT
to 6. That is, have to add/modify arch/arm/mm/Kconfig.
This patch is for handle it in each ARCH Kconfig.
