net: atp: drop ancient parallel-port Ethernet driver

This driver is old and almost certainly entirely unused. The two other
parallel port Ethernet drivers (de600/de620) were removed by Paul
Gortmaker in commit 168e06ae26dd ("drivers/net: delete old parallel
port de600/de620 drivers"), but this driver remained. Drop it - Paul's
reasoning applies here as well. To quote him:

"The parallel port is largely replaced by USB [...] Let us not pretend
that anyone cares about these drivers anymore, or worse - pretend that
anyone is using them on a modern kernel."
