it8380dev: modify hwtimer and LPC wake up
1. In combinational mode and clock source is 8MHz,
if timer 3 counter register always equals to 7, then timer 4 will be a
32-bit MHz free-running counter.
2. Fix TIMER_32P768K_CNT_TO_US(), each count should be 30.5175 us,
not 32.768us.
3. Fix TIMER_CNT_8M_32P768K().
4. Make sure LPC wake up interrupt is enabled before entering doze /
deep doze mode.
