    xen/arm: mm: Mark check_memory_layout_alignment_constraints as unused
    
    Clang will throw an error if a function is unused unless you tell
    to ignore it. This can be done using __maybe_unused.
    
    While modifying the declaration, update it to match prototype of similar
    functions (see build_assertions). This helps to understand that the sole
    purpose of the function is to hold BUILD_BUG_ON().
