hexagon: irq: add prototype for arch_do_IRQ()

Browse Source 
Clang warns:

  arch/hexagon/kernel/vm_events.c:83:6: warning: no previous prototype for function 'arch_do_IRQ' [-Wmissing-prototypes]
     83 | void arch_do_IRQ(struct pt_regs *regs)
        |      ^
  arch/hexagon/kernel/vm_events.c:83:1: note: declare 'static' if the function is not intended to be used outside of this translation unit
     83 | void arch_do_IRQ(struct pt_regs *regs)
        | ^
        | static

This function is only called from assembly but the irq header is a
reasonable place to put a prototype to silence the warning.
