ide: drop dsc_handle argument from ide_pc_intr()

Browse Source 
* Add 'int dsc' argument to ->pc_callback method.

* Call ide_tape_handle_dsc() internally in ide_tape_callback()
  if dsc argument is set and update ide_pc_intr() accordingly.

There should be no functional changes caused by this patch.
