x86: make HAVE_SPARSE_IRQ support selectable
Ingo said sparse_irq is some intrusive. need to make it selectable to make it simple, remove irq_desc as parameter in some functions. (ack, eoi, set_affinity). may need to make member if irq_chip to take irq_desc, or struct irq later. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
