spi: Fixes for v7.4-rc1

As well as a few driver specific fixes we have a couple of core fixes
here.  One avoids requesting interrupts until we have validated that we
have a SPI device, avoiding triggering warnings on boot.  The other
avoids a request for a zero length scatterlist triggering a BUG_ON() in
swiotlb on 64k page systems, this was due to using both DIV_ROUND_UP()
and min() to compute lengths.
