This is a supplement to the patch:1936126210a56b6d1b033d6d940669413dd6e1b0 Due to the automatic wrapping of MTD devices during the open() process, the legacy registration methods ftl_initialize() and bchdev_register() are no longer required for MTD device registration for user code. So we have adjusted the registration method for MTD devices in nuttx/boards, replacing the previous approach using ftl_initialize() with register_mtddriver().
