can: peak_usb: upgrade core to data bittiming specs
Upgrade PEAK-System USB adapters core to the new data structures (names) and callbacks added for the support of the CANFD extension. This specific patch does the mandatory changes to support new data bittiming specs. Signed-off-by: Stephane Grosjean <s.grosjean@peak-system.com> Signed-off-by: Marc Kleine-Budde <mkl@pengutronix.de>
