    linuxkpi: Add <linux/font.h>
    
    The header defines the minimum to allow the DRM generic code to build.
    The only function used so far is `get_default_font()`, as part of a
    DRM-specific panic handler. We do not use this panic handler on FreeBSD.
    
    For now, it returns a NULL value. It should probably map to a vt(4)
    font.
    
    The DRM generic code started to use it in Linux 6.10 as part of the
    panic handler.
