       a) Moved mram init into m_can_dev_setup function by then
          clocks are enabled and prevent probe failure.
       b) Added the platform init ops in m_can_plat_ops and
          moved mram init into it.

https://lore.kernel.org/netdev/20221021095833.62406-7-vivek.2311@xxxxxxxxxxx/
    1: Addressed review comment given by kernel test robot.
       a) Addressed missing prototypes warnings.

    2: Addressed review comment given by  Marc Kleine-Budde
       a) Sorted the declaration of local variable by reverse Christmas 
          tree.
       b) Used syscon_regmap_lookup_by_phandle_args to get the syscon
          Base Address and offset.
       c) Used FIELD_PREP instead of logical operation.
       d) Used regmap_read_poll_timeout API to give timeout condition
          for ECC cfg done status instead of using while loop counter.
       e) Moved all the ECC mcaros in m_can.c file and changed the name
          with a common prefix M_CAN.
       f) Moved ECC init into platform init function called during m_can
          device setup.
