Christophe Leroy 96c79fef22 powerpc/8xx: Remove offset in SPRN_M_TWB

SPRN_M_TWB contains the address of task PGD minus an offset which
compensates the offset required when accessing the kernel PGDIR.
However, since commit ac9f97ff8b ("powerpc/8xx: Inconditionally use
task PGDIR in DTLB misses") and commit 33c527522f ("powerpc/8xx:
Inconditionally use task PGDIR in ITLB misses") kernel PGDIR is not
used anymore in hot paths.

Remove this offset which was added by
commit fde5a9057f ("powerpc/8xx: Optimise access to swapper_pg_dir")
