Implement wakeup interrupts on amd64. Provide a dummy implementation for
i386 such that we can call the necessary hooks in the suspend/resume code
without adding #ifdefs. Tweak the arm64 implementation such that we can
call the hooks earlier as this is necessary to mask MSI and MSI-X
interrupts on arm64.
