vfio: platform: introduce vfio-platform-base module
To prepare for vfio platform reset rework let's build vfio_platform_common.c and vfio_platform_irq.c in a separate module from vfio-platform and vfio-amba. This makes possible to have separate module inits and works around a race between platform driver init and vfio reset module init: that way we make sure symbols exported by base are available when vfio-platform driver gets probed. The open/release being implemented in the base module, the ref count is applied to the parent module instead.
