[PATCH v8 12/12] Documentation: PCI: Add documentation for Live Update

Add documentation files for the PCI subsystem's participation in Live
Update.

These documentation files are generated from the kernel-doc comments
in the PCI Live Update source code. They describe the File-Lifecycle
Bound (FLB) API, the device tracking API, and the specific policies
applied to preserved devices (such as bus number inheritance and bus
mastering preservation).
