[PATCH] powerpc/8xx: fix setting of pagetable for Abatron BDI debug tool.

Commit 8c8c10b90d88 ("powerpc/8xx: fix handling of early NULL pointer dereference") moved the loading of r6 earlier in the code. As some functions are called inbetween, r6 needs to be loaded again with the address of swapper_pg_dir in order to set PTE pointers for the Abatron BDI. Fixes: 8c8c10b90
