Marek Vasut 99312c377f can: ifi: Fix clock generator configuration
The clock generation does not match reality when using the CAN IP
core outside of the FPGA design. This patch fixes the computation
of values which are programmed into the clock generator registers.

First, there are some off-by-one errors which manifest themselves
only when communicating with different controller, so those are
fixed.

Second, the bits in the clock generator registers have different
meaning depending on whether the core is in ISO CANFD mode or any
of the other modes (BOSCH CANFD or CAN2.0). Detect the ISO CANFD
mode and fix handling of this special case of clock configuration.

Finally, the CAN clock speed is in CANCLOCK register, not SYSCLOCK
register, so fix this as well.
