Finish converting CONFIG_SYS_CACHELINE_SIZE to Kconfig

Browse source 
We move the SYS_CACHE_SHIFT_N options from arch/arm/Kconfig to
arch/Kconfig, and introduce SYS_CACHE_SHIFT_4 to provide a size of 16.
Introduce select statements for other architectures based on current
usage.  For MIPS, we take the existing arch-specific symbol and migrate
to the generic symbol.  This lets us remove a little bit of otherwise
unused code.
