The ppce500 machine doesn't have to stick to hardware limitations,
as it's defined as being fully device tree based.
Thus we can change the initial PCI slot ID to 0x1 which gives us a
whopping 31 PCI devices we can support with this machine now!

We have a params struct that allows us to expose differences between
e500 machine models. Include PCI slot information there, so we can have
different machines with different PCI slot topology.

This should help us to:
- More easily add or remove machine initialization arguments without
having to change every single machine init function;
- More easily make mechanical changes involving the machine init
functions in the future;
- Let machine initialization forward the init arguments to other
functions more easily.
This change was half-mechanical process: first the struct was added with
the local ram_size, boot_device, kernel_*, initrd_*, and cpu_model local
variable initialization to all functions. Then the compiler helped me
locate the local variables that are unused, so they could be removed.

This gives the kernel a paravirtualized machine to target, without
requiring both sides to pretend to be targeting a specific board
that likely has little to do with the host in KVM scenarios. This
avoids the need to add new boards to QEMU, just to be able to
run KVM on new CPUs.
