parport: Remove register_sysctl_table from parport_device_proc_register

parport: Remove register_sysctl_table from parport_device_proc_register

This is part of the general push to deprecate register_sysctl_paths and
register_sysctl_table. We use a temp allocation to include both port and
device name in proc. Allocated mem is freed at the end. The unused
parport_device_sysctl_template struct elements that are not used are
removed.
