When fixing the CAN clock frequency,
fb12797ab1fe ("can: kvaser_usb: get CAN clock frequency from device"),
I introduced a regression.
For Leaf devices based on M32C, the firmware expects bittiming parameters
calculated for 16MHz clock. Regardless of the actual clock frequency.
This regression affects M32C based Leaf devices with non-16MHz clock.
Also correct the bittiming constants in kvaser_usb_leaf.c, where the limits
are different depending on which firmware/device being used.
Once merged to mainline, I'll backport these fixes for the stable kernels.
