[rt-smart] porting c906 and D1s to mm (#6848) 

* [rv64/bsp] porting to mm

* [mm] report more info for debugging

* [fix] code format

* [libcpu/c906] porting to RTOS

* [fix] using rtdbg api

* [fix] add return

* [fix] report more information for debugging

* [fix] use assert 0 for unrecoverable error
