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.

- EC Lib
This wraps Blizzard driverlib and implements the EC chip interface defined
by Google. See below diagram for architecture.

src/platform/ec/chip_interface/*.
