Remove the CAN_HAS_RX_TIMESTAMP Kconfig helper symbol in order to allow enabling CAN RX timestamps in the API regardless of driver support. This simplifies application prj.conf settings across board supporting/not supporting RX timestamps considerably. CAN drivers not supporting RX timestamps already initialize the timestamp to 0 for received frames. Signed-off-by: Henrik Brix Andersen <hebad@vestas.com>
