Nordic platforms measure ticks in cycles of a 32 KiHz clock for which the minimum compare delay is 2 ticks. The test assumed an upper bound of four ticks delay per loop iteration, resulting from alignment at various layers. This delay is met on Nordic for tick rates at or below 16384, but is too short for the default 32768 Hz tick rate. Instrumentation confirms that the usleep test loop body on Nordic at 32 KiHz ticks takes 3 ticks as the optimum delay, only when a debug probe is active. In other circumstances it can take either 5 or 6 ticks, depending on timer alignment and stability. Relax the upper bound for platforms using this system timer at the highest rate. Closes #17965.
