PCI: layerscape: Allow to compile as module

Browse Source 
The layerscape pcie host controller could also be compiled as module.
Add the necessary infrastructure to allow building as module instead of
only as builtin driver.

Since the driver doesn't expose an irqchip controller, it is also safe to
be removed during runtime.
