Warning with "qemu-s390x -cpu max"

With the current state of the QEMU master branch (commit d9ccf33f), running "qemu-s390x -cpu max" emits a warning about the "msa5-base" CPU feature:

$ ./qemu-s390x -cpu max /bin/ls
qemu-s390x: warning: 'msa5-base' requires 'kimd-sha-512'.
qemu-s390x: warning: 'msa5-base' requires 'klmd-sha-512'.
...

I think "-cpu max" should be working just fine, without a warning, in user mode, too, so we should consider to remove the "msa5-base" feature from "max" in user mode.
