    cpu/amd/microcode: Update microcode parser to handle expanded blob files
    
    The Family 15h microcode files provided by AMD are approximately 1.5x
    larger than the Family 10h and K8 files currently in the coreboot tree.
    As a result, they exceed the 2k/update size limit of coreboot's update
    mechanism.
    
    To handle the increased microcode size, coreboot's AMD microcode file
    format was changed to 4k/update in a separate commit to the blobs
    repository.  This patch allows parsing of that updated format.
