powerpc/64s: Remove POWER4 support
POWER4 has been broken since at least the change 49d09bf2a6 ("powerpc/64s: Optimise MSR handling in exception handling"), which requires mtmsrd L=1 support. This was introduced in ISA v2.01, and POWER4 supports ISA v2.00. Signed-off-by: Nicholas Piggin <npiggin@gmail.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
