sh: Kill off broken direct-mapped cache mode.
Forcing direct-mapped worked on certain older 2-way set associative parts, but was always error prone on 4-way parts. As these are the norm these days, there is not much point in continuing to support this mode. Most of the folks that used direct-mapped mode generally just wanted writethrough caching in the first place.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

- help
- Selecting this option will configure the caches to be direct-mapped,
- even if the cache supports a 2 or 4-way mode. This is useful primarily
- for debugging on platforms with 2 and 4-way caches (SH7750R/SH7751R,
- SH4-202, SH4-501, etc.)
-
- Turn this option off for platforms that do not have a direct-mapped
- cache, and you have no need to run the caches in such a configuration.
