    graphics/nvidia-drm-515-kmod: Fix build on CURRENT with iosys-map.h
    
    Commit f8ab2f5bae1d added the linux/iosys-map.h header to base in order
    to support 5.18+ versions of drm-kmod. This messes with nvidia-drm's
    conftest logic as on recent enough CURRENT versions it will see iosys-map
    and assume it can use it, but the drm-kmod version in use is 5.15,
    which wants to use the older dma_buf_map.
    
    This adds a patch on the port side to override nvidia-drm's detector
    and force the use of dma_buf_map on the 5.15 port.
