NgATM: deprecate

Support for ATM NICs was removed prior to FreeBSD 12.  At the time it
was unclear if this code was still useful without it.  Now the time has
come to finish removing support.

Add DREPRECATION NOTICEs to the manpages and gone_in(14, ...) warnings
in the constructors (or module init for ngatmbase).
