    xen/arm64: Make sure we get all debug output
    
    Starting in the wrong ELx mode I get the following debug output:
    
    ...
    - Current EL 00000004 -
    - Xen must be entered in NS EL2 mode -
    - Boot failed -
    
    The output of "Please update the bootloader" is missing here, because
    string concatenation in gas, unlike in C, keeps the \0 between each
    individual string.
    
    Make sure this is output, too. With this, we get
    
    ...
    - Current EL 00000004 -
    - Xen must be entered in NS EL2 mode -
    - Please update the bootloader -
    - Boot failed -
    
    as intended.
