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.
