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().
