This is part of the general push to deprecate register_sysctl_paths and
register_sysctl_table. Simply change the full path "dev/parport/default"
to point to an already existing set of table entries (vars). We also
remove the unused elements from parport_default_table.

To make sure the resulting directory structure did not change we
made sure that `find /proc/sys/dev/ | sha1sum` was the same before and
after the change.
