spi: spi-loopback-test: Allow skipping delays 



A 100 ms delay is inserted between tests by default in order to "detect
the individual tests when using a logic analyzer".  However, such delays
are unnecessary when using this module for automated regression testing,
so allow them to be disabled with a module parameter.
