    target/cortex_m: fix debug reason after reset halt
    
    [1] removed target_halt() from cortex_m_assert_reset()
    It broke debug_reason tracking and the previous reason
    was shown after reset halt.
    
    Set debug_reason to DBG_REASON_DBGRQ during reset halt
    preparation.
    
    Fixes: [1] commit 226085065bdf ("target/cortex_m: drop useless 
target_halt() call")
