    mcu/fe310: Remove global ctrs initialization from start.s
    
    Call to __libc_init_array is now present in baselibc start.c.
    
    This removes double initialization of constructors.
    It also removes call to atexit since for embedded systems when
    main() ends it means system reboot so there is no need for cleanup
    here.
    Other MCU's code don't bother with global destructors too.
