[PATCH] sh: Move CPU subtype configuration to its own Kconfig
Currently the CPU subtype options are cluttering up arch/sh/Kconfig somewhat.
Given that, this moves all of that in to its own arch/sh/mm/Kconfig. Things
like cache configuration are also moved to this new location.
This also adds support for strict CPU tuning on newer cores, which requires
the addition of as-option.
