I don't think it's necessary to have both an alias
and a label here. What do you use the alias for?

Yes, don't use aliases. If you really need a specific timer to be used
then there must be some feature it has or doesn't have (e.g. always
on, output compare pin, specific clock, etc.) Put those those
properties in DT if that is the case. See OMAP timers for a complex
example of this.
