Allow the timer core to change the smp affinity of the broadcast
irq by setting CLOCK_EVT_FEAT_DYNIRQ flag.

This reduces interrupt pressure and wakeups on CPU0 as well as
reducing the number of timer broadcast IPIs.

Did you test this patch on a tegra2 ?

Yes, I haven't spotted anything bad, but don't know if I should look
out for specific oddities?

I was wondering if you tested it because the changelog was the same than the similar change you did previously so I wanted to know if you assumed the behavior or if you tested it.

So, no problem.

Thanks !
