OK maybe that wasn't the most elegant solution.

This is not how I would solve this today.

I would simply remove/comment out the IRQ from the timer
that cannot be used for clockevent from the device tree
(apparently it doesn't work anyway), and make the code only
pick a timer with a valid interrupt assigned as clock event,
while a timer without interrupt can be used for clock source.

This has the upside of not needing any special aliases or
chosen things.
