For various historical reasons the initialisation of the isapc machine is closely
intertwined with the initialisation of the pc machine, which is preventing some
future improvements to the pc machine initialisation logic.

Since the consensus [1] was that the isapc is still useful for testing and running
older OSs, this series splits the isapc machine and its main initialisation
routine pc_init_isa() into a separate isapc.c file to reduce the maintenance
burden on pc machine developers.
