    x86/ucode: Trivial further cleanup
    
     * Drop unused include in private.h.
     * Used explicit width integers for Intel header fields.
     * Adjust comment to better describe the extended header.
     * Drop unnecessary __packed attribute for AMD header.
     * Fix types and style.
    
    No functional change.
