mmc: tmio: sdhi: Move tap_pos to private data
Move the tap_pos variable, which is the HS200/HS400/SDR104 calibration offset, into private data, so it can be passed around. This is done in preparation for the HS400 mode, which needs to adjust this value. Signed-off-by: Marek Vasut <marek.vasut+renesas@gmail.com> Cc: Masahiro Yamada <yamada.masahiro@socionext.com>
