v2:
Fix for idefloppy_ioctl name change from Stephen Rothwell.

Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* Move ->ticks field from struct ide_floppy_obj to ide_drive_t.

* Move idefloppy_transfer_pc() to ide-atapi.c and make
  ide_transfer_pc() use it.

* Always use ide_transfer_pc as a handler in ide_issue_pc().

* Remove no longer used idefloppy_start_pc_transfer(),
  ide*_transfer_pc() and 'handler' argument from ide_issue_pc().

* Make ide_transfer_pc() static.

While at it:

* idefloppy_transfer_pc() -> ide_delayed_transfer_pc()

* IDEFLOPPY_TICKS_DELAY -> IDEFLOPPY_PC_DELAY

* ->ticks -> ->pc_delay

There should be no functional changes caused by this patch.

  and convert ide-{atapi,floppy,tape}.c to use them.

* Remove no longer used ide*_create_request_sense_cmd(),
  ide*_retry_pc() and 'retry_pc' argument from ide_pc_intr().

* Make ide_queue_pc_head() static.

Add 'struct ide_atapi_pc request_sense_pc' and 'request request_sense_rq' to
ide_drive_t and use them instead of fields in struct ide_{floppy,tape}_obj.

* Add pointer to the current packet command (struct ide_atapi_pc *pc)
  to ide_drive_t and use it instead of the pointer in struct ide_*_obj.

* Use drive->pc in ide_{issue,transfer}_pc() and ide_pc_intr()
  instead of 'pc' argument.
