powerpc/hwirq: Remove stale forward irq_chip declaration

Since commit identified below, the forward declaration of
struct irq_chip is useless (was struct hw_interrupt_type at that time)

Remove it, together with the associated comment.

Fixes: c0ad90a32f ("[PATCH] genirq: add ->retrigger() irq op to consolidate hw_irq_resend()")
