In order to reduce pop-noise at powering up/down of the DACs and Drivers, these components have to be handled in a specific sequence. Headset, Handsfree, and Earphone drivers are now registered as PGA components to ensure DACs are enabled first.
Also, add a pop_time of 1 ms to leave time for DACs to settle before continuing power up/down sequence.
