powerpc/mm: Switch obsolete dssall to .long
commit d51f86cfd8e378d4907958db77da3074f6dce3ba upstream.
The dssall ("Data Stream Stop All") instruction is obsolete altogether
with other Data Cache Instructions since ISA 2.03 (year 2006).
LLVM IAS does not support it but PPC970 seems to be using it.
This switches dssall to .long as there is no much point in fixing LLVM.
