* 3 = ON
* These will be multiplied by 2 before given to the driver PM code

* (most notably _PWR_COMM) allowing more versatile PM.
* The PM actions:
* _PWR_OFF = board support for regulators, clocks, etc so no
* power to device.
* _PWR_STDBY = board support to put device in reset. Device is
* useless but powered. No communication possible.
* _PWR_COMM = Device is powered but in SW standby. Communication
* is possible and device retains programming.
* _PWR_ON = Full power with active output.
