help
when rtio is use with spi each driver holds a context with which blocking
api calls use to perform spi transactions. this queue needs to be as deep
as the longest set of spi_buf_sets used, where normal spi operations are
used (equal length buffers). it may need to be slightly deeper where the
spi buffer sets for transmit/receive are not always matched equally in
length as these are transformed into normal transceives.
