Subject: [PATCH 5/7] MIPS: dec: Remove dec_irq_dispatch()

Currently, dec_irq_dispatch() is exclusively invoked by int-handler.S.
Inline the do_IRQ call into int-handler.S to silence the compiler
warning.

Fix follow error with gcc-14 when -Werror:

arch/mips/dec/setup.c:780:25: error: no previous prototype for ‘dec_irq_dispatch’ [-Werror=missing-prototypes]
  780 | asmlinkage unsigned int dec_irq_dispatch(unsigned int irq)
