Subject: [PATCH 3/3] genirq: Remove setup_percpu_irq() and remove_percpu_irq()

Precedence: bulk

Only users of setup_percpu_irq() were in MIPS, they have been converted
to use request_percpu_irq() variants. Also remove_percpu_irq() have no
users.

Hence remove setup_percpu_irq() as well as remove_percpu_irq().
