Subject: [PATCH v7 4/7] ARM: dts: rockchip: add clockevent attribute to rockchip timers

All rockchip timers present in the DT act as clockevent.
It is possible to specify timer role using DT attribute.
Mark them accordingly.

Also this patch specify that for timer should be called init
function specified with CLOCKEVENT_OF_DECLARE().

Without the commit boot warnings will appear because clock
framework will try initialize them as clocksource.
