x86/microcode/AMD: Remove unused save_microcode_in_initrd_amd() declarations

commit 3ef0740 upstream.

Commit

  a7939f0 ("x86/microcode/amd: Cache builtin/initrd microcode early")

renamed it to save_microcode_in_initrd() and made it static. Zap the
forgotten declarations.

No functional changes.
