hexagon: vm_fault: mark do_page_fault() as static

Clang warns:

  arch/hexagon/mm/vm_fault.c:36:6: warning: no previous prototype for function 'do_page_fault' [-Wmissing-prototypes]
     36 | void do_page_fault(unsigned long address, long cause, struct pt_regs *regs)
        |      ^
  arch/hexagon/mm/vm_fault.c:36:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
     36 | void do_page_fault(unsigned long address, long cause, struct pt_regs *regs)
        | ^
        | static

This function is not used outside of this translation unit, so mark it
as static.
