[PATCH] powerpc/cpm2: fix building fs_enet driver as a module.

[Grant Likely]

From: Grant Likely <grant.likely@secretlab.ca>

Building the fs_enet driver as a modules fails because it cannot
access the global cpm2_immr symbol.

Hey Ben and Kumar,

Just found this while testing some unrelated changes.  Technically
this is a bug fix that should go into 2.6.29, but it looks like an
old problem and probably nobody is getting bitten by it.  I don't
think the world is going to end if it misses the 2.6.29 release.

applied to next.  (I agree this isn't worth .29 at this point, if  
anyone cares they can lobby for it in .29.1)
