PM: Optional beeping during resume from suspend to RAM
Add a feature allowing the user to make the system beep during a resume from
suspend to RAM, on x86_64 and i386.
This is useful for the users with broken resume from RAM, so that they can
verify if the control reaches the kernel after a wake-up event.
