commit 49f274c72357d2d74cba70b172cf369768909707 upstream.
Unify and move compile-time known information into new struct
kvaser_usb_driver_info, in favor of run-time checks.
All Kvaser USBcanII supports listen-only mode and error counter
reporting.

commit b3b6df2c56d80b8c6740433cff5f016668b8de70 upstream.
Use correct bittiming limits depending on device. For devices based on
USBcanII, Leaf M32C or Leaf i.MX28.
Fixes: 080f40a6fa28 ("can: kvaser_usb: Add support for Kvaser CAN/USB devices")
Fixes: b4f20130af23 ("can: kvaser_usb: add support for Kvaser Leaf v2 and usb mini PCIe")
Fixes: f5d4abea3ce0 ("can: kvaser_usb: Add support for the USBcan-II family")
