ide-tape: add ide_tape_io_buffers() helper
* Add ide_tape_io_buffers() helper which is a wrapper for idetape_{in,out}put_buffers() and convert idetape_pc_intr() to use it. * Remove no longer used idetape_io_buf typedef. There should be no functional changes caused by this patch. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>---
