mmc: core: Don't use close-ended rw for SDUC
The SDUC spec expects CMD22 to get squeezed between CMD23 and the
read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25.
At this early stage of adoption, we want to avoid an amid stream of
fixes & quirks of bogus hw, that tends to apply extra logic specifically
around auto-cmd12 & auto-cmd23.
Let's leave close-ended out for now, and re-consider this should those
cards become ubiquitous, if any.
It also means that BLK_FEAT_FUA will not be used for I/O, but instead we
will rely on BLK_FEAT_WRITE_CACHE.
