can: gs_usb: document the USER_ID feature
The widely used open source firmware candleLight has optional support
for reading/writing of an user defined value into the device's flash.
This is indicated by the GS_CAN_FEATURE_USER_ID feature. The
corresponding request are GS_USB_BREQ_GET_USER_ID and
GS_USB_BREQ_SET_USER_ID.
This patch documents these values.
