This driver uses delayed work to perform periodic battery state read out. This delayed work is not stopped across suspend and resume cycle. The read out can occur early in the resume cycle. In case of an I2C variant of this hardware, that read out triggers I2C transfer. That I2C transfer may happen while the I2C controller is still suspended, which produces a WARNING in the kernel log. Fix this by introducing trivial PM ops, which stop the delayed work before the system enters suspend, and schedule the delayed work right after the system resumes.
