The PoP states: "The message-security-assist extension 5 requires the secure-hash-algorithm (SHA-512) capabilities of the message-security-assist extension 2 as a prereq- uisite. (March, 2015)" As SHA-512 won't be supported in the near future, let's just drop the feature from the "max" model. This avoids the warning and allows us for making the "max" model match the "qemu" model (except for compat machines). We don't lose much, as we only implement the function stubs for MSA, excluding any real subfunctions.
