hexagon: process: add internal prototype for do_work_pending()

Browse Source 
Clang warns:

  arch/hexagon/kernel/process.c:155:5: warning: no previous prototype for function 'do_work_pending' [-Wmissing-prototypes]
    155 | int do_work_pending(struct pt_regs *regs, u32 thread_info_flags)
        |     ^
  arch/hexagon/kernel/process.c:155:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
    155 | int do_work_pending(struct pt_regs *regs, u32 thread_info_flags)
        | ^
        | static

This function is only referenced from assembly, so it does not technically
need a prototype.  Add one right above the definition anyways to clear up
the warning.
