[PATCH] xen/common: device_tree: Fix MISRA C 2012 Rule 8.7 violation

[Xenia Ragiadakou <burzalodowa@xxxxxxxxx>]

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.
