We currently support building one kernel that supports a bunch of
different boards.  The hardcoding of this workaround was harmless so far
because it was conditional on a symbol that was never defined, but now
you'll be enabling this workaround on any kernel that simply has support
for mpc8315erdb.  That is not acceptable unless you show it's harmless
on all those other boards.
