David Hendricks 9a3e056af5 daisy v1.02: power sequencing updates ...

Note: This will not work on older (0.94 boards).

- Use power button (KB_PWR_ON) to drive power sequencing events and
  disable EC_PWRON. This is because EC_PWRON and KB_PWR_ON shared an
  external interrupt line. Daisy v2.x will fix this so that both can
  be enabled. Note: KB_PWR_ON is active low, wihle EC_PWRON is active
  high.

- Relay power button state to PMIC. Also, since we are driving
  PMIC_PWRON instead of PMIC_ACOK now, so updated the naming.

- Add a keyboard power button debounce period to avoid accidentally powering
  the system back on after keyboard power-off.
