powerpc/8xx: Fix regression introduced by cache coherency rewrite
After upgrading to the latest kernel on my mpc875 userspace started running incredibly slow (hours to get to a shell, even!). I tracked it down to commit 8d30c14cab30d405a05f2aaceda1e9ad57800f36, that patch removed a work-around for the 8xx. Adding it back makes my problem go away.
