can: kvaser_usb: get CAN clock frequency from device
The CAN clock frequency is used when calculating the CAN bittiming parameters. When wrong clock frequency is used, the device may end up with wrong bittiming parameters, depending on user requested bittiming parameters. To avoid this, get the CAN clock frequency from the device. Various existing Kvaser Leaf products use different CAN clocks.
