HID: Intel-thc-hid: Intel-quicki2c: Add output report support 



Add support for HID output reports in the intel-quicki2c driver by
implementing the output_report callback in the HID low-level driver
interface.

This enables proper communication with HID devices that require
output report functionality, such as setting device configuration or
updating device firmware.
