[PATCH] pnp: parport: adjust pnp_register_driver signature

Remove the assumption that pnp_register_driver() returns the number of devices
claimed.

parport_pc_init() does nothing with "count", so remove it.  Then nobody uses
the return value of parport_pc_find_ports(), so make it void.  Finally, update
pnp_register_driver() usage.
