Benjamin Valentin 669104d841 cpu/sam0_common: SPI: don't perform DMA transfer for small buffers 
Setting up a DMA transfer can take longer than sending out a buffer
byte by byte if the buffer is small.

DMA only shows advantages for large buffers, using it for every transfer
will cause a net slowdown.

Since we did not come up with a good way to determine the treshold based
on the SPI frequency, just use a fixed buffer for now so that DMA can be
used without slowing things down overall.
