This commit fixes multiple bugs caused by incorrect calls to
can_enter_reset_mode() and can_exit_reset_mode. Example test
scripts also updated to match new runners.
This commit does the following
- Add power management lock to CAN driver so that APB frequency does not change
whilst CAN driver is in use
- Fix incorrect flag in can_transmit()
- Refactor can_driver_install() and can_driver_uninstall() so that critical sections
are shorter
- Fix CAN gpio configuration bug on RX pin. Closes#2302
