power: supply: qti_battery_charger: add some more properties
To support userspace application and testing, add some more properties under USB power supply and qcom-battery class. To show USB connector temperature, following property is added. - /sys/class/power_supply/usb/temp To support restricted charging similar to legacy targets, following parameters are added. - /sys/class/qcom-battery/restrict_cur - /sys/class/qcom-battery/restrict_chg To show whether the Type-C sink/source connected is compliant, following parameter is added. - /sys/class/qcom-battery/usb_typec_compliant To show the custom USB_TYPE for Quick charge adapters like HVDCP, HVDCP3 etc., following parameter is added. - /sys/class/qcom-battery/usb_real_type.
