Henrik Brix Andersen e397b85eb8 drivers: can: calculate a default SJW value
Change the CAN timing calculation APIs to automatically calculate a default
(Re-)Synchronization Jump Width (SJW) value. The calculated value can be
overwritten by the caller if desired.

This allows automatically scaling the SJW according to the number of Time
Quanta (TQ) used for phase segment 2 instead of relying on a compile-time
fallback value defined in devicetree.

This reduces the can_set_timing()/can_set_timing_data() API functions to
simple setters (with validation).

Fixes: #63033

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
