Remove it for clean code.

This change also adds support for reset of CDX devices. With VFIO enabled on CDX devices, user-space applications can also exercise DMA securely via IOMMU on these devices. This change adds the VFIO CDX driver and enables the following ioctls for CDX devices: - VFIO_DEVICE_GET_INFO: - VFIO_DEVICE_GET_REGION_INFO - VFIO_DEVICE_RESET Signed-off-by: Nipun Gupta <nipun.gupta@amd.com> Reviewed-by: Pieter Jansen van Vuuren <pieter.jansen-van-vuuren@amd.com> Tested-by: Nikhil Agarwal <nikhil.agarwal@amd.com> Link: https://lore.kernel.org/r/20230531124557.11009-1-nipun.gupta@amd.com Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
