dummy_hcd: Switch to hrtimer transfer scheduler The dummy_hcd transfer scheduler assumes that the internal kernel timer frequency is set to 1000Hz to give a polling interval of 1ms. Reducing the timer frequency will result in an anti-proportional reduction in transfer performance. Switch to a hrtimer to decouple this association.
