	  When RTIO is used 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.
