[PATCH V8 1/3] irq: Add flags to request_percpu_irq function

In the next changes, we track the interrupts but we discard the timers as
that does not make sense. The next interrupt on a timer is predictable.

But, the API request_percpu_irq does not allow to pass a flag, hence specifying
if the interrupt type is a timer.

Solve this by passing a 'flags' parameter to the function and change all the
callers to pass IRQF_TIMER when the interrupt is a timer interrupt, zero
otherwise.

For now, in order to prevent a misusage of this parameter, only the IRQF_TIMER
flag is a valid parameter to be passed to the request_percpu_irq function.
