Andrew Cooper f42dff8429 x86/ucode: Refine the boundary checks for Entrysign
After initial publication, the SB-7033 / CVE-2024-36347 bulletin was updated
to list Zen5 CPUs as vulnerable.  Use Fam1ah as an upper bound, and adjust the
command line documentation.

When the Zen6 (also Fam1ah processors) model numbers are known, they'll want
excluding from the range.
