In the Pine64 PinePhone, the stk3310 chip is powered by a regulator that is disabled at system boot and can be shut off during suspend. To ensure that the chip properly initializes, both after boot and suspend, we need to manage this regulator. Additionally if the chip is shut off in suspend, we need to make sure that it gets reinitialized with the same parameters after resume.
