drivers: can: stm32: correct timing_max parameters
The timing_max parameters defined in the stm32 bxcan driver don't match the
register description in the reference manuals.
- sjw does have only 2 bits representing 1 to 4 tq.
- phase_seg1 and phase_seg2 max is one tq higher.
I have checked the following reference manuals and all match:
- RM0090: STM32F405, F415, F407, F417, F427, F437 AND F429
- RM0008: STM32F101, F102, F103, F105, F107 advanced arm-based mcus
- RM0351, RM0394: all STM32L4
- RM0091: all STM32F0 with CAN support
