x86/ucode: Extend AMD digest checks to cover Zen5 CPUs

AMD have updated the SB-7033 advisory to include Zen5 CPUs.  Extend the digest
check to cover Zen5 too.

In practice, cover everything until further notice.

Observant readers may be wondering where the update to the digest list is.  At
the time of writing, no Zen5 patches are available via a verifiable channel.
