hexagon: mm: mark paging_init() as static

Clang warns:

  arch/hexagon/mm/init.c:89:13: warning: no previous prototype for function 'paging_init' [-Wmissing-prototypes]
     89 | void __init paging_init(void)
        |             ^
  arch/hexagon/mm/init.c:89:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
     89 | void __init paging_init(void)
        | ^
        | static

This function is only used within this translation unit, so mark it static
as suggested.
