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.
