ARM: sunxi-mmc: Add mmc support for sun6i / A31
The mmc hardware on sun6i has an extra reset control that needs to be de-asserted prior to usage. Also the FIFO address is different. Signed-off-by: Hans de Goede <hdegoede@redhat.com> [wens@csie.org: use setbits_le32 for reset control, drop obsolete changes, rewrite different FIFO address handling, add commit message] Signed-off-by: Chen-Yu Tsai <wens@csie.org> Acked-by: Ian Campbell <ijc@hellion.org.uk>
