soc/braswell/acpi/DPTF: Write TCHG state on AC connect.

DPTF should update the charger cooling device state during
    boot time and every 3 seconds after boot. But 3 seconds polling
    doesn't seems to be working with current version of DPTF.
    This impacts charging since DPTF writes states 4 when charger
    is not connected at boot time. On connecting the charger,
    DPTF doesn't write 0 to enable charging. This issue is addressed
    by calling the PPPC function to read cooling device state  and passing
    the value to SPPC to set cooling device state. This doesn't
    compromise safety since DPTF can override this value
    later based on the platform thermal condition. Also this provides
    additional safety measure in the unlikely event that DPTF crashes
    and is not re-spawned by OS. With this patch even after DPTF crashes,
    if the power adapter is plugged it would still allow the system to
    charge correctly.
