examples/mtdpart:Register MTD devices using the mtd_register method

[jingfei195887]

Summary

1. 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. The new method is now changed to register_mtddriver

2. Some code for space release and deregistration has been added, and certain error handling methods have been updated.

Test

Run the examples/mtdpart in sim:nsh for test an test is passed
