* Update ide_unregister() users to set 'init_default' and 'restore' flags.
* No need to set 'init_default' flag in ide_register_hw() if the setup done
by init_hwif_default() is going to be overridden by ide_init_port_hw().
* No need to set 'init_default' and 'restore' flags in cleanup_module().
There should be no functionality changes caused by this patch.

This flag was never being set in the code so remove it. By the way, the
code in the second patch was being executed unconditionally, i.e. in case
pc->retries > IDEFLOPPY_MAX_PC_RETRIES is true (actually that is the only case
when the outer if-test passed), !test_bit(PC_ABORT, &pc->flags)
was always true so the comment is now incorrect and has to go.

This change is rather temporary and is in preparation of using generic commands
as is the case with ide-cd and the uniform cdrom layer (i.e. init_cdrom_command())
However, before this happens, we'll have to remove all typedefs and teach
idefloppy_create_mode_sense_cmd() to work directly on u8 buffers.
Also, since idefloppy_get_capability_page() was used to read only the sfrp bit,
rename the latter so that the name reflects what it does.

There were two almost identical function names in ide-floppy.c, which makes
their distinction almost impossible. While ide_floppy_release() cleans up the
object after the last reference to it has been dropped, idefloppy_release() is
the blkdev .release method from struct block_device_operations which releases
that last reference.
Rename ide_floppy_release() to idefloppy_cleanup_obj() in order to make its
purpose more clear.

The new API fits nicely, except maybe for the QLA case where a bit of
