irqchip/gicv3-its: Split PCI/MSI code from the core ITS driver
It is becoming obvious that having the PCI/MSI code in the same
file as the the core ITS code is giving people implementing non-PCI
MSI support the wrong kind of idea.
In order to make things a bit clearer, let's move the PCI/MSI code
out to its own file. Hopefully it will make it clear that whoever
thinks of hooking into the core ITS better have a very strong point.
We use a temporary entry point that will get removed in a subsequent
patch, once the proper infrastructure is added.
