Patch 1 pins the protocol module before the device becomes visible.
Previously try_module_get() ran after device_register(), so a forced
module unload in between left pi->proto dangling from the moment the
device appeared on the bus.

Patch 2：fix parport attach idr_alloc for port numbers > 0

I have become cautious now, for fear of causing a disaster, so I removed
this patch. The other patches sent this time have undergone simple
compilation tests and simple tests such as rmmod. Since I don't have the
relevant hardware to test this patch, out of caution, I removed it this
time.

in v3:
1.ata: pata_parport: pin the protocol module before device_register() no
  changes
2.Add ata: pata_parport: fix parport attach for port numbers > 0
