parport: fix a kernel-doc markup

Browse Source 
The kernel-doc markup inside share.c is actually for
__parport_register_driver. The actual goal seems to be
to document parport_register_driver().

So, fix the existing markup and add a new one.

*
* If using the non device model:
* The driver's attach() function may block. The port that
* attach() is given will be valid for the duration of the
* callback, but if the driver wants to take a copy of the
* pointer it must call parport_get_port() to do so. Calling
* parport_register_device() on that port will do this for you.
*
* The driver's detach() function may block. The port that
* detach() is given will be valid for the duration of the

* pointer it must call parport_get_port() to do so.
*
*
* Returns 0 on success. The non device model will always succeeds.
* but the new device model can fail and will return the error code.
