Subject: [PATCH 2/5] x86/microcode/AMD: Remove unused save_microcode_in_initrd_amd() declarations

From: "Borislav Petkov (AMD)" <bp@...en8.de>

Commit

  a7939f016720 ("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.
