or1k: Remove secondary functions in cache manager

Move the code of the _CPU_OR1K_Cache_{enable,disable}_* functions into the
equivalent exported _CPU_cache_{enable,disable}_* functions instead, and
then delete them, in order to reduce the code indirection and aid
readability.

This does not touch the currently unused prefetch, writeback, and lock
functions.
