Subject: [PATCH v3] arch/x86/microcode: Mark early_parse_cmdline() as __init

Fix section mismatch warning reported by modpost:
  .text:early_parse_cmdline() -> .init.data:boot_command_line

The function early_parse_cmdline() is only called during init and
accesses init data, so mark it __init to match its usage.
