Subject: [PATCHv7 13/26] vfio: amba: add the VFIO for AMBA devices module to Kconfig

Enable building the VFIO AMBA driver. VFIO_AMBA depends on VFIO_PLATFORM,
since it is sharing a portion of the code, and it is essentially implemented
as a platform device whose resources are discovered via AMBA specific APIs
in the kernel.
