soc: qcom: add ADSP PDCharger ULOG driver The Qualcomm PMIC PDCharger ULOG driver provides access to logs of the ADSP firmware PDCharger module in charge of Battery and Power Delivery on modern systems. Implement trace events as a simple rpmsg driver with an 1s interval to retrieve the messages. The interface allows filtering the messages by subsystem and priority level, this could be implemented later on.
