drivers: can: fix can_configure() when CAN-FD is enabled

Currently, can_configure() pass a hard-coded 0 for the data bitrate
(which is only used for CAN-FD), breaking this API for CAN-FD enabled
applications.

Instead pass in the provided bitrate for both arbitration phase and data
phase.

Fixes: #34375
