Ananth N Mavinakayanahalli 20d323c8cf powerpc/sstep: Check instruction validity against ISA version before emulation 
commit 8813ff49607eab3caaf40fe8929b0ce7dc68e85f upstream.

We currently unconditionally try to emulate newer instructions on older
Power versions that could cause issues. Gate it.

Fixes: 350779a29f ("powerpc: Handle most loads and stores in instruction emulation code")
