It is used in the write path, I think I meant to use it for subpage
writes, when I thought it would just mean to transfer only parts of the
page to the controller.
However, as the subpage discussion basically concluded in not using it
for now on this controller, we can as well transfer the complete page
(page_sz). Or is there another case in which vf610_nfc_write_buf could
be called with less than page_sz?
