    xen/common: device_tree: Fix MISRA C 2012 Rule 8.7 violation
    
    The function __dt_n_size_cells() is referenced only in device_tree.c.
    Change the linkage of the function from external to internal by adding
    the storage-class specifier static to the function definition.
    
    This patch aims to resolve indirectly a MISRA C 2012 Rule 8.4 violation
    warning.
