genirq/irqdomain: Update irq_domain_ops.activate() signature
The irq_domain_ops.activate() callback has no return value and no way to tell the function that the activation is early. The upcoming changes to support a reservation scheme which allows to assign interrupt vectors on x86 only when the interrupt is actually requested requires: - A return value, so activation can fail at request_irq() time - Information that the activate invocation is early, i.e. before request_irq().
