genirq: Remove __request_percpu_irq() helper
With the IRQ timing stuff being gone, there is no need to specify a flag
when requesting a percpu interrupt. Not only IRQF_TIMER was the only flag
(set of flags actually) allowed, but nobody ever passed it.
Get rid of __request_percpu_irq(), which was only getting 0 as flags, and
promote request_percpu_irq_affinity() as its replacement.
