Rex Feany e0908085fc 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 8d30c14cab,
that patch removed a work-around for the 8xx. Adding it
back makes my problem go away.
