Liav A 9252a892bb Kernel: Abstracts x86 reboot and shutdown specific methods
We move QEMU and VirtualBox shutdown sequences to a separate file, as
well as moving the i8042 reboot code sequence too to another file.

This allows us to abstract specific methods from the power state node
code of the SysFS filesystem, to allow other architectures to put their
methods there too in the future.
