[PATCH] HID: intel-ish-hid: Update ishtp bus match to support device ID table

[Zhang Lixu]

The ishtp_cl_bus_match() function previously only checked the first entry
in the driver's device ID table. Update it to iterate over the entire
table, allowing proper matching for drivers with multiple supported
protocol GUIDs.
