powerpc/lib/sstep: Use l1_dcache_bytes() instead of opencoding
Don't opencode dcache size retrieval based on whether that's ppc32 or ppc64. Use l1_dcache_bytes() Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Link: https://lore.kernel.org/r/6c608fd4795e2d8ea1a0a449405a0087f76d8bb3.1642752375.git.christophe.leroy@csgroup.eu
