This series introduces new polling mode and fixes bug.

- Introduce new polling mode for short size transfer. Either the estimated
  transfer time is estimated to exceed 200us, or polling loop actually exceeds
  200us, it switches to irq mode.
- Fix a bug of register overwrite.
- Minor corrections.
