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>
