    agp.4: Add a deprecation notice to the man page
    
    The driver is giant-locked and thus already prints a deprecation warning
    when attaching.  The device file interface was broken in 14.0 and 14.1,
    see commit 12500c14281d, but it took a very long time for anyone to
    notice, and in that case it was only because of some code which probes
    all device files.
    
    Relnotes:       yes
