drivers: can: sam: use bosch m_can timing parameter initializers

The minimum/maximum CAN timing parameters for the Atmel SAM CAN driver uses
the wrong values for the minimum, nominal phase segment values. The same
goes for the maximum, nominal SJW value.

Using the static initializers fixes these and aligns them to both the Bosch
M_CAN manual and the Atmel SAM E70 family data sheet.

Fixes: #58429
