can: m_can.c: fix setup of CCCR register: clear CCCR NISO bit before checking can.ctrlmode
Inside m_can_chip_config(), when setting up the new value of the CCCR,
the CCCR_NISO bit is not cleared like the others, CCCR_TEST, CCCR_MON,
CCCR_BRSE and CCCR_FDOE, before checking the can.ctrlmode bits for
CAN_CTRLMODE_FD_NON_ISO.
This way once the controller was configured for CAN_CTRLMODE_FD_NON_ISO,
this mode could never be cleared again.
This fix is only relevant for controllers with version 3.1.x or 3.2.x.
Older versions do not support NISO.
