can: gs_usb: add HW timestamp mode bit

Newer versions of the widely used open source firmware candleLight
support hardware timestamps. The support is activated by setting the
GS_CAN_MODE_HW_TIMESTAMP in the GS_USB_BREQ_MODE request.

Although timestamp support is not yet supported by this driver, add
the missing bit for documentation purpose.
